Two days? I'd say more like two hours. And your review will be more efficient if you use the features available on the AAMC practice exams. On your score report, they group the questions in each section into subtopics (such as acid/base problems, gravitation, cell biology, etc.), and give a tally of how many you got right in each subtopic. So if you have an area of glaring weakness (like magnetism problems in my case), it will stand out right away. Plus, if you click that answer tally, you'll go straight to the WRONG answers you got in that category, which saves time. Finally, AAMC offers you a drop-down menu of reasons why you got a question wrong, and the score report keeps a running tally for you of each kind of error. This helps you analyze mistakes you made which may not have to do with the test content, such as changing right answers to wrong ones or misreading a question. (For example, on one test I found that 20% of my errors were due to changing right answers to wrong ones! That was quite an eye-opener.)
The Kaplan score reports don't have any of those fancy features, so it takes longer to review one of their tests. But even for those, 2-3 hours should be sufficient.
