Hi Quantum2003:
I used to write questions for the GRE and GMAT and my wife managed 2 Kaplan test prep centers, so I have some ideas about this.
ETS uses several standard question types. Being able to identify quickly which type of question you are being asked is very helpful for moving through the test efficiently. There are also good strategies for eliminating incorrect answers.
Depending on how DS learns, a couple of hours with a good tutor from Kaplan or some other service and a few practice tests might do the job. A full Kaplan course is probably not a good idea.
I hope this helps--good luck!
Ken
