My top ten ways to improve the MCAT, in more or less order of increasing absurdity:
1. Type essays rather than write them. This is going to be a reality for the people taking the computer version.
2. Let people take the MCAT at their convenience, rather than two test dates per year. This is already done for the DAT and GRE and it's really great.
3. Show you your scores first, and then you can decide whether you want to void them or report them to the schools.
4. Partial credit for answers that were on the right track. Let them check your work in the test booklet for every question you missed.
5. No physics or biology. I'd love to just have chemistry and nothing else on both science sections.
6. No passages. Discrete questions only for BS and PS.
7. Proctors should walk around the room and advise students that they may want to recheck certain questions that they've missed.
8. VR passages should be short plays that are acted out for the benefit of the entire testing room. They'll be just as hard to understand as the written passages, but at least they'll be entertaining.
9. Essay topics should be things that actually matter to adolescents. Like, how do you get a gorgeous person of your preferred sexual persuasion to notice you? Extra credit can be given to test-takers who succeed in seducing said gorgeous person during the test.
10. A person who misses every single question on the MCAT automatically shoots the moon and gets a perfect 45 score.
