The Warburg Pincus Reporting Persons do not expressly affirm membership in a group with the Silver Lake Reporting Persons, and disclaim beneficial ownership of any Shares held by the Silver Lake Reporting Persons, Igloo, Parent or Stockholder (as defined below). Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that the Warburg Pincus Reporting Persons or any of their respective affiliates are the beneficial owners of any Shares beneficially owned by the Silver Lake Reporting Persons, Igloo, Parent or Stockholder for purposes of Section 13(d) of the Exchange Act, the rules promulgated thereunder or for any other purpose. As of the date hereof, the Silver Lake Reporting Persons, the Warburg Pincus Reporting Persons, Igloo and Parent may be deemed to have shared beneficial ownership over the 57,554,795 Shares beneficially owned by Stockholder.

Item 3. Source and Amount of Funds or Other Consideration

On May 3, 2010, concurrently with the execution of the Merger Agreement (as defined in Item 4 below), Parent, Pearson plc (“Pearson”) and Pearson DBC Holdings Inc., a subsidiary of Pearson (“Stockholder”), entered into a voting agreement (the “Voting Agreement”) with respect to 57,554,795 Shares beneficially owned by Stockholder pursuant to which Stockholder agreed to vote such Shares in favor of approving and adopting the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Merger (as defined in Item 4 below). No Shares were purchased by the Reporting Persons pursuant to the Voting Agreement and thus no funds were used by the Reporting Persons for such purpose.

The information set forth in response to this Item 3 is qualified in its entirety by reference to the Voting Agreement, a copy of which is filed herewith as Exhibit 2 and is hereby incorporated herein by reference.

Item 4. Purpose of Transaction

The information set forth or incorporated in Item 3 is hereby incorporated herein by reference.

On May 3, 2010, Parent entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Igloo Merger Corporation, a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), and the Issuer. Pursuant to the Merger Agreement, and upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent. At the effective time of the Merger, the Issuer will become a wholly owned subsidiary of Parent, and each outstanding Share (other than Shares held in treasury by the Issuer or owned by Parent or Merger Sub, or shares held by dissenting stockholders who properly exercise appraisal rights under applicable law) will be converted into the right to receive $33.86 in cash, without interest. Following the effective time of the Merger, it is contemplated that the Shares will cease to be listed on the New York Stock Exchange and will become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act.

The consummation of the Merger is subject to various conditions, including but not limited to (i) the representations and warranties in the Merger Agreement being true and correct as of the effective time of the Merger, subject to certain exceptions, and (ii) receipt of certain regulatory approvals as set forth in the Merger Agreement.

Under the Merger Agreement, upon consummation of the Merger, the certificate of incorporation of the Issuer will be restated and the bylaws of the Issuer will be amended in their entirety, in each case until thereafter amended in accordance with such restated certificate of incorporation or amended bylaws, as applicable, and applicable law. Under the Merger Agreement, at the effective time of the Merger, (i) the Issuer is required to deliver evidence reasonably satisfactory to Parent of the resignation of all directors of the Issuer and, upon consummation of the Merger, the directors of Merger Sub immediately prior thereto will become the directors of the Issuer as the surviving corporation of the Merger and (ii) upon consummation of the Merger, the officers of the Issuer at the effective time of the Merger will be the officers of the Issuer as the surviving corporation of the Merger.

As an inducement to Parent to enter into the Merger Agreement, Pearson, Parent and Stockholder entered into the Voting Agreement. Pursuant to the Voting Agreement, Stockholder agreed, subject to certain exceptions, that at any meeting of the stockholders of the Issuer, however called, at any adjournment thereof, and in connection with any written consent of the stockholders of the Issuer, Stockholder would (i) appear at such meeting, or otherwise cause the Shares beneficially owned by it to be counted as present for calculating a quorum, and (ii) vote (or deliver a written consent in lieu thereof) all Shares beneficially owned by it which it is entitled to vote (or deliver a written consent with respect thereto) at the time of any vote or written consent (A) to adopt the Merger Agreement, and approve any actions related thereto as and when such Merger Agreement or such other actions are submitted for the consideration and vote of the stockholders of the Issuer, (B) against any Alternative Proposal (as defined in the Merger Agreement), without regard to the terms of such Alternative Proposal, or any other transaction, proposal, agreement or action made in opposition to adoption of the Merger Agreement or in competition or inconsistent with the Merger and the other transactions contemplated by the Merger Agreement and (C) against any other action that is intended to or could prevent, impede, or, in any material respect, interfere with, delay the transactions contemplated by the Merger Agreement. Pursuant to the Voting Agreement, Stockholder granted Parent a proxy to vote the Shares beneficially owned by Stockholder in the manner described in the immediately preceding sentence. Immediately after the execution of the Merger Agreement and the Voting Agreement, Stockholder executed a written consent approving and adopting the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Merger.

The Reporting Persons may seek to influence the management or the Board of Directors of the Issuer with respect to its business and affairs, including having the Issuer take action to facilitate consummation of the Merger. Other than as described above, each of the Reporting Persons reports that neither it, nor to its knowledge, any of the other persons named in Item 2 of this Schedule 13D, currently has any plan or proposal which relates to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D, although the Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.

The information set forth in response to this Item 4, including the foregoing summary of the Merger Agreement, the Voting Agreement and the transactions contemplated thereby, including the Merger, is qualified in its entirety by reference to the Voting Agreement and the Merger Agreement, copies of which are filed herewith as Exhibits 2 and 3, respectively, and are hereby incorporated herein by reference.

Item 5. Interest in Securities of the Issuer

The information set forth or incorporated in Items 2, 3, 4 and 6 is hereby incorporated herein by reference.

(a), (b)		The following disclosure assumes that there are 95,213,472 Shares outstanding, which the Issuer represented in the Agreement and Plan of Merger was the number of outstanding Shares as of April 29, 2010. The following disclosure further assumes that Stockholder beneficially owns 57,554,795 Shares, which Stockholder represented in the Voting Agreement was the number of outstanding Shares it beneficially owned as of May 3, 2010.

		As a result of the Voting Agreement, the Reporting Persons may be deemed for the purposes of Rule 13d-3 promulgated under the Exchange Act to beneficially own 57,554,795 Shares, representing, for the purposes of Rule 13d-3, approximately 60.4% of the outstanding Shares. The Reporting Persons, however, expressly disclaim beneficial ownership of such Shares, and this statement shall not be construed as an admission that the Reporting Persons are, for any or all purposes, the beneficial owners of the securities covered by this statement.

		Except to the extent that they may be deemed to have any such power by virtue of the Voting Agreement, the Reporting Persons do not have sole power to vote or to direct the vote, shared power to vote or to direct the vote, or the sole or shared power to dispose or to direct the disposition of any of the Shares. The Reporting Persons may be deemed in certain circumstances, as more fully described in Item 4, to have the shared power with the Stockholder to vote 57,554,795 Shares. However, the Reporting Persons (i) are not entitled to any rights as a stockholder of the Issuer as to the Shares that are subject to the Voting Agreement and (ii) expressly disclaim any beneficial ownership of the Shares that are covered by the Voting Agreement.

		Except as set forth in this Item 5, (i) none of the Reporting Persons beneficially own any Shares, (ii) to the best knowledge of the Silver Lake Reporting Persons, none of the Silver Lake Managing Members beneficially own any Shares and (iii) to the best knowledge of the Warburg Pincus Reporting Persons, none of the persons set forth on Schedule I hereto beneficially own any Shares.

(c)		Except for the execution and delivery of the Voting Agreement and Merger Agreement, (i) none of the Reporting Persons has effected any transaction in the Shares during the past 60 days, (ii) to the best knowledge of the Silver Lake Reporting Persons, none of the Silver Lake Managing Members has effected any transaction in the Shares during the past 60 days and (iii) to the best knowledge of the Warburg Pincus Reporting Persons, none of the persons set forth on Schedule I hereto has effected any transaction in the Shares during the past 60 days.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Except for the Merger Agreement and Voting Agreement described above, to the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise), including, but not limited to, transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, among the persons named in Item 2 or between such persons and any other person, with respect to any securities of Issuer, including any securities pledged or otherwise subject to a contingency the occurrence of which would give another person voting power or investment power over such securities other than standard default and similar provisions contained in loan agreements.
