This amendment No. 1 to the Schedule 13D filed by GP Strategies Corporation ("GP
Strategies"), Jerome I. Feldman, and Scott N. Greenberg on October 30, 2003,
relates to the Common Stock, par value $0.01 per share (the "Common Stock") of
GSE Systems, Inc., 7133 Rutherford Road, Baltimore, MD 21244. This amendment No.
1 is being filed (i) by GP Strategies to report the disposition of all of the
shares of Common Stock it had beneficially owned, (ii) by Mr. Feldman and Mr.
Greenberg, to report the acquisition of certain shares of Common Stock, and (ii)
by GP Strategies and Mr. Greenberg to report that they are no longer the
beneficial owner of more than five percent of the outstanding shares of Common
Stock.

Item 2.  Identity and Background

This statement is filed by GP Strategies, Jerome I. Feldman and Scott N.
Greenberg. The present principal occupation of Mr. Greenberg is Chief Executive
Officer and Chief Financial Officer of GP Strategies. Mr. Feldman is Chairman of
the Executive Committee of the Board of Directors of GP Strategies, but is no
longer an officer of GP Strategies. Accordingly, Mr. Feldman may no longer be
deemed to have voting or dispositive control over securities beneficially owned
by GP Strategies.

Item 5.  Interest in Securities of the Issuer

(a) On September 30, 2005, GP Strategies distributed all of its shares of Common
Stock to GP Strategies stockholders on a pro rata basis (the "Spin-Off"). As a
result of the Spin-Off, GP Strategies no longer owns any shares of Common Stock.
In the Spin-Off, Mr. Feldman and Mr. Greenberg received 165,753 shares and 6,147
shares of Common Stock, respectively. As a result, following the Spin-Off, Mr.
Feldman and Mr. Greenberg beneficially owns 382,753 shares (including 217,000
shares subject to options owned by Mr. Feldman which are currently exercisable)
and 106,147 shares of Common Stock (including 100,000 shares subject to options
owned by Mr. Greenberg which are currently exercisable), representing
approximately 4.3% and 1.2% of the outstanding shares of Common Stock (based on
a total of 8,999,706 shares of Common Stock outstanding as of August 1, 2005),
respectively.

(c) In the past 60 days, the sole transaction in Common Stock effected by GP
Strategies was the Spin-Off. In the past 60 days, Mr. Feldman and Mr. Greenberg
did not effect any transactions in Common Stock, but they received shares of
Common Stock in the Spin-Off, as described in (a), above.

(e) As a result of the Spin-Off, as of September 30, 2005, GP Strategies and Mr.
Greenberg each ceased to be the beneficial owner of more than five percent of
the outstanding shares of Common Stock.
