                         MUNIYIELD QUALITY FUND II, INC.

The Benefits and
Risks of Leveraging

MuniYield Quality Fund II, Inc. utilizes leveraging to seek to enhance the yield
and net asset value of its Common Stock. However, these objectives cannot be
achieved in all interest rate environments. To leverage, the Fund issues
Preferred Stock, which pays dividends at prevailing short-term interest rates,
and invests the proceeds in long-term municipal bonds. The interest earned on
these investments is paid to Common Stock shareholders in the form of dividends,
and the value of these portfolio holdings is reflected in the per share net
asset value of the Fund's Common Stock. However, in order to benefit Common
Stock shareholders, the yield curve must be positively sloped; that is,
short-term interest rates must be lower than long-term interest rates. At the
same time, a period of generally declining interest rates will benefit Common
Stock shareholders. If either of these conditions change, then the risks of
leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates. Of course, increases in short-term interest rates would reduce (and even
eliminate) the dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value of the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange) may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed-rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in these securities.

Swap
Agreements

The Fund may also invest in swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified bond, basket of bonds, or index in return
for periodic payments based on a fixed or variable interest rate or the change
in market value of a different bond, basket of bonds or index. Swap agreements
may be used to obtain exposure to a bond or market without owning or taking
physical custody of securities.

DEAR SHAREHOLDER

For the six months ended April 30, 2003, the Common Stock of MuniYield Quality
Fund II, Inc. had a net annualized yield of 6.05%, based on a period-end per
share net asset value of $13.67 and $.410 per share income dividends. Over the
same period, the total investment return on the Fund's Common Stock was +6.54%,
based on a change in per share net asset value from $13.27 to $13.67, and
assuming reinvestment of $.408 per share ordinary income dividends.

For the six-month period ended April 30, 2003, the Fund's Auction Market
Preferred Stock had an average yield of 1.25% for Series A, .98% for Series B
and 1.05% for Series C.

For a description of the Fund's total investment return based on a change in the
per share market value (as measured by the trading price of the Fund's shares on
the New York Stock Exchange), and assuming reinvestment of dividends, please
refer to the Financial Highlights section of the Financial Statements included
in this report. As a closed-end fund, the Fund's shares may trade in the
secondary market at a premium or discount to the Fund's net asset value. As a
result, total investment returns based on changes in the Fund's market value can
vary significantly from total investment return based on changes in the Fund's
net asset value.

The Municipal Market Environment

During the six-month period ended April 30, 2003, amid considerable weekly and
monthly volatility, long-term fixed income interest rates generally declined.
Geopolitical tensions and volatile equity valuations continued to overshadow
economic fundamentals as they have for most of the last 12 months. Reacting to
the strong U.S. equity rally that began last October, fixed income bond yields
remained under pressure in November 2002, as U.S. equity markets continued to
strengthen. During November, the Standard & Poor's 500 (S&P 500) Index rose an
additional 5.5%. Equity prices were supported by further signs of U.S. economic
recovery, especially improving labor market activity. In late November,
third-quarter 2002 U.S. gross domestic product growth was 4%, well above the
second-quarter 2002 rate of 1.3%. Financial conditions were also strengthened by
a larger-than-expected reduction in short-term interest rates by the Federal
Reserve Board in early November. The Federal Funds target rate was lowered 50
basis points (0.50%) to 1.25%, its lowest level since the 1960s. This action by
the Federal Reserve Board was largely viewed as being taken to bolster the
sputtering U.S. economic recovery. Rebounding U.S. equity markets and the
prospects for a more substantial U.S. economic recovery pushed long-term U.S.
Treasury yield levels to 5.10% by late November.

However, into early 2003, softer equity prices and renewed investor concerns
about U.S. military action against Iraq and North Korea again pushed bond prices
higher. Reacting to disappointing holiday sales and corporate managements'
attempts to scale back analysts' expectation of future earnings, the S&P 500
Index declined more than 10% from December 2002 to February 2003. Fearing an
eventual U.S./Iraq military confrontation in 2003, investors again sought the
safety of U.S. Treasury obligations and the prices of fixed income issues rose.
By the end of February 2003, U.S. Treasury bond yields had declined
approximately 40 basis points to 4.67%.

Bond yields continued to fall into early March. Once direct U.S. military action
against Iraq began, bond yields quickly rose. Prior uncertainty surrounding the
Iraqi situation was obviously removed and early U.S. military successes fostered
the hope that the conflict would be quickly and positively concluded.
Concurrently, the S&P 400 Index rose over 6% as investors, in part, sold fixed
income issues to purchase equities in anticipation of a strong U.S. economic
recovery once the Iraqi conflict was resolved. By mid-March, U.S. Treasury bond
yields again rose to above 5%. However, as there was growing sentiment that
hostilities may not be resolved in a matter of weeks, U.S. Treasury bond yields
again declined to end the month at 4.81%.

For the six months ended April 30, 2003, long-term U.S. Treasury bond yields
ratcheted back to near 5% by mid-April, as U.S. equity markets continued to
improve and the safe-haven premium U.S. Treasury issues had commanded prior to
the beginning of the Iraqi conflict continued to be withdrawn. However, with the
quick positive resolution of the Iraqi war, investors quickly resumed their
focus on the fragile U.S. economic recovery. Business activity in the United
States has remained sluggish, especially job creation. Investors have also been
concerned that the recent SARS outbreak would have a material, negative impact
on world economic conditions, especially in China and Japan. First quarter 2003
U.S. gross domestic product was released in late April initially estimating U.S.
economic activity to be growing at 1.6%, well below many analysts' assessments.
These factors, as well as the possibility that the Federal Reserve Board could
again lower short-term interest rates to encourage more robust U.S. economic
growth, pushed bond prices higher during the last two weeks of the period. By
April 30, 2003, long-term U.S. Treasury bond yields had declined to almost
4.75%. Over the past six months, long-term U.S. bond yields fell more than 20
basis points.

For the six months ended April 30, 2003, long-term tax-exempt bond yields also
fell modestly. Yield volatility was reduced relative to that seen in U.S.
Treasury issues, as municipal bond prices were much less sensitive to worldwide
geopolitical pressures on a daily and weekly basis. Tax-exempt bond yields
generally followed their taxable counterparts higher, responding to a more
positive U.S. fixed income environment and continued slow economic growth. After
rising approximately 10 basis points in November 2002 to 5.30%, municipal bond
yields generally declined through February 2003. At February 28, 2003, long-term
tax-exempt revenue bond yields, as measured by the Bond Buyer Revenue Bond
Index, fell to approximately 5.05%. However, similar to U.S. Treasury bond
yields, once military action began in Iraq, municipal bond yields rose sharply
to nearly 5.20% before declining to approximately 5.10% by the end of April.
Over the past six months, long-term tax-exempt bond yields fell approximately 11
basis points, slightly less than U.S. Treasury obligations.

A number of factors have combined to generate consistently strong demand for
municipal bonds throughout the six-month period ended April 30, 2003. Generally
weak U.S. equity markets have supported continued positive demand for tax-exempt
products as investors have sought the relative security of fixed income issues.
Also, with tax-exempt money market rates near 1%, the demand for longer maturity
municipal issues has increased as investors have opted to buy longer maturity
issues rather than remain in cash reserves. Additionally, investors received
approximately $30 billion in January 2003 from bond maturities, coupon income
and proceeds from early redemptions. However, these positive demand factors were
not totally able to offset the increase in tax-exempt new-issue supply,
preventing more significant declines in tax-exempt bond yields. This modest
underperformance has served to make municipal bonds a particularly attractive
purchase relative to their taxable counterparts. Throughout most of the yield
curve, municipal bonds have been able to be purchased at yields near or
exceeding those of comparable Treasury issues. Compared to their recent
historical averages of 82% - 88% of U.S. Treasury yields, municipal bond yield
ratios in their current 95% - 105% range are likely to prove attractive to
long-term investors.

Declining U.S. equity markets and escalating geopolitical pressures have
resulted in reduced economic activity and consumer confidence. It is important
to note that, despite all the recent negative factors impeding the growth of
U.S. businesses, the U.S. economy still grew at an approximate 2.5% rate for all
of 2002, twice that of 2001. Similar expansion is expected for early 2003. Lower
oil prices, reduced geopolitical uncertainties, increased Federal spending for
defense, and a likely Federal tax cut are all factors which should promote
stronger economic growth later this year. However, it is questionable to expect
that business and investor confidence can be so quickly restored as to trigger
dramatic, explosive U.S. economic growth and engender associated, large-scale
interest rate increases. The resumption of solid economic growth is likely to be
a gradual process accompanied by equally graduated increases in bond yields.
Moderate economic growth, especially within a context of negligible inflationary
pressures, should not greatly endanger the positive fixed income environments
tax-exempt products currently enjoy.

Portfolio Strategy

For the six months ended April 30, 2003, our principal portfolio strategy was to
maintain the Fund's slightly defensive structure and competitive tax-exempt
yield. We implemented


                                      2 & 3


                                 MuniYield Quality Fund II, Inc., April 30, 2003

this strategy by remaining fully invested and favoring premium coupon bonds. We
also pursued the strategy of extending out the yield curve. The municipal yield
curve has become exceptionally steep during the past year, with the ten-year
area of the curve exhibiting considerable volatility. When available, we
purchased premium coupon bonds in the 20-year - 25-year maturity range and sold
bonds with ten-year - 15-year maturities. The larger issuance of municipal bonds
during the period compared to levels one year ago assisted in implementing this
strategy. We adopted our current strategy in recognition of relatively low
municipal yields within the background of a cautious economic environment.
Despite significant monetary and fiscal stimulus, the U.S. economy grew at
sub-par levels. Additionally, significant international events contributed to
the uncertainty facing the U.S. economy. Looking ahead, we expect to remain
essentially fully invested and to retain the Fund's current defensive structure.
We will wait until the domestic economy strengthens further before adopting a
more defensive position.

During the period, the Fund's borrowing costs remained at very low levels,
generally between 1% and 1.50%. These attractive borrowing levels, in
combination with a steep tax-exempt yield curve, generated a substantial income
benefit to the Fund's Common Stock shareholder from the leveraging of the
Preferred Stock. Further material declines in short-term interest rates would
require significant easing of monetary policy by the Federal Reserve Board.
While such action is not expected, an increase in short-term interest rates by
the Federal Reserve Board is even less anticipated. We expect the Fund's
short-term borrowing costs to remain at current attractive levels for the
foreseeable future. However, should the spread between short-term and long-term
interest rates narrow, the benefits of leverage will decline, and as a result,
reduce the yield on the Fund's Common Stock. (For a more complete explanation of
the benefits and risks of leveraging, see page 1 of this report to
shareholders.)

We appreciate your ongoing interest in MuniYield Quality Fund II, Inc., and we
look forward to serving your investment needs in the months and years to come.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

MuniYield Quality Fund II, Inc. (the "Fund") is registered under the Investment
Company Act of 1940 as a non-diversified, closed-end management investment
company. The Fund's financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require the use of management accruals and estimates. These unaudited
financial statements reflect all adjustments, which are, in the opinion of
management, necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal, recurring nature. The Fund
determines and makes available for publication the net asset value of its Common
Stock on a weekly basis. The Fund's Common Stock is listed on the New York Stock
Exchange under the symbol MQT. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at their fair value as determined in good faith
by or under the direction of the Board of Directors of the Fund, including
valuations furnished by a pricing service retained by the Fund, which may
utilize a matrix system for valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movement and movements in the securities
markets. Losses may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

o Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at a specific
price or yield. Upon entering into a contract, the Fund deposits and maintains
as collateral such initial margin as required by the exchange on which the
transaction is effected. Pursuant to the contract, the Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the contract is
closed, the Fund records a realized gain or loss equal to the difference between
the value of the contract at the time it was opened and the value at the time it
was closed.

o Options -- The Fund is authorized to write covered call options and purchase
put options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the option written. When a security is purchased or sold through
an exercise of an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from (or added to)
the proceeds of the security sold. When an option expires (or the Fund enters
into a closing transaction), the Fund realizes a gain or loss on the option to
the extent of the premiums received or paid (or gain or loss to the extent the
cost of the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

o Forward interest rate swaps -- The Fund is authorized to enter into forward
interest rate swaps. In a forward interest rate swap, the Fund and the
counterparty agree to pay or receive interest on a specified notional contract
amount, commencing on a specified future effective date, unless terminated
earlier. The value of the agreement is determined by quoted fair values received
daily by the Fund from the counterparty. When the agreement is closed, the Fund
records a realized gain or loss in an amount equal to the value of the
agreement.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML

proceeds from the issuance of Preferred Stock. For the six months ended April
30, 2003, FAM reimbursed the Fund in the amount of $4,499.

For the six months ended April 30, 2003, the Fund reimbursed FAM $4,928 for

MANAGED DIVIDEND POLICY

The Fund's dividend policy is to distribute all or a portion of its net
investment income to its shareholders on a monthly basis. In order to provide
shareholders with a more consistent yield to the current trading price of shares
of Common Stock of the Fund, the Fund may at times pay out less than the entire
amount of net investment income earned in any particular month and may at times
in any month pay out such accumulated but undistributed income in addition to
net investment income earned in that month. As a result, the dividends paid by
the Fund for any particular month may be more or less than the amount of net
investment income earned by the Fund during such month. The Fund's current
accumulated but undistributed net investment income, if any, is disclosed in the
Statement of Assets, Liabilities and Capital, which comprises part of the
Financial Information included in this report.

MuniYield Quality Fund II, Inc. seeks to provide shareholders with as high a
level of current income exempt from Federal income taxes as is consistent with
its investment policies and prudent investment management by investing primarily
in a portfolio of long-term, high-grade municipal obligations, the interest on
which is exempt from Federal income taxes in the opinion of bond counsel to the
issuer. The Fund invests primarily in insured municipal bonds.

This report, including the financial information herein, is transmitted to
shareholders of MuniYield Quality Fund II, Inc. for their information. It is not
a prospectus. Past performance results shown in this report should not be
considered a representation of future performance. The Fund has leveraged its
Common Stock and intends to remain leveraged by issuing Preferred Stock to
provide the Common Stock shareholders with a potentially higher rate of return.
Leverage creates risks for Common Stock shareholders, including the likelihood
of greater volatility of net asset value and market price of shares of the
Common Stock, and the risk that fluctuations in the short-term dividend rates of
the Preferred Stock may affect the yield to Common Stock shareholders.
Statements and other information herein are as dated and are subject to change.
