[FORM OF OPINION]

The Board of Directors
Apollo Group, Inc.
4615 E. Elwood Street
Phoenix, Arizona  85040

August __, 2000


To the Board of Directors:

We have acted as tax advisors for Apollo Group, Inc. (the "Company") in
connection with the public offering of up to 5,750,000 shares of University of
Phoenix Online common stock. Terms defined in the prospectus (the "Prospectus")
that is part of the Registration Statement on Form S-3 filed by the Company with
the Securities and Exchange Commission on August ___, 2000 are used herein as
therein defined.

In rendering our opinion, we have assumed, subject to shareholder approval of
the Tracking Stock Proposal, that the authorization, issuance, and sale of
University of Phoenix Online common stock as well as the reclassification of the
Company's existing shares of Class A common stock and Class B common stock to
shares of Apollo Education Group Class A common stock and Apollo Education Group
Class B common stock, respectively, will be implemented and consummated in the
manner and utilizing the procedures currently contemplated in the Registration
Statement, and have assumed that such procedures will not be modified in any
material respect by any applicable supplement.

     Our opinion as it relates to the reclassification addresses only those
holders of Company Class A and Class B common stock who hold such stock as a
capital asset as defined in section 1221(a) of the Internal Revenue Code. Our
opinion does not address all aspects of United States federal income taxation
that may be relevant to a holder of Company common stock in light of such
holder's particular circumstances. We have assumed that the holders of Company
common stock are not subject to special rules, such as those that may be
applicable to a holder that is a broker-dealer, tax-exempt organization, S
corporation or other pass-through entity,

mutual fund, small business investment company, regulated investment company,
insurance company or other financial institution. Moreover, in rendering this
opinion, no ruling has been sought from the Internal Revenue Service (the
"Service") and, in this regard, the Service has announced that it will not issue
advance rulings on the classification of an instrument that has certain voting
and liquidation rights in an issuing corporation but whose dividend rights are
determined by reference to the earnings of a segregated portion of the issuing
corporation's assets, including assets held by a subsidiary. Our opinion is not
binding on the Service. In addition, there are no court decisions or other
authorities bearing directly on the classification of instruments with
characteristics similar to those of the University of Phoenix Online common
stock. It is possible, therefore, that the Service could assert that the
issuance of University of Phoenix Online common stock could result in taxation
to the Company. We are, however, of the opinion that the Service would not
prevail in such an assertion.

Based upon the foregoing, it is our opinion that, for federal income tax
purposes:

1.   University of Phoenix Online common stock will be considered common stock
     of the Company and, accordingly, neither the holders of University of
     Phoenix Online common stock nor the Company will recognize any income, gain
     or loss as a result of the issuance of the University of Phoenix Online
     common stock. Under current law, the purchase, ownership, and disposition
     of the University of Phoenix Online common stock will be treated in the
     same manner as the purchase, ownership, and disposition of the Apollo
     Education Group common stock.

2.   The holders of Company stock will recognize no income, gain, or loss on the
     issuance of the University of Phoenix Online common stock to purchasers who
     acquire such stock for cash.

3.   The holders of Company common stock will recognize no income, gain, or loss
     upon the reclassification of their Class A Common Stock and Class B Common
     Stock to Apollo Education Group Class A Common Stock and Apollo Education
     Group Class B Common Stock, respectively.

4.   Purchasers of University of Phoenix Online common stock will recognize no
     income, gain, or loss on their purchase of the University of Phoenix Online
     common stock in exchange for cash.


                                                                             (2)

stock.
