So I've recently (as of 10 minutes ago) decided to switch my test date to May 11th instead of April 16th. I keep missing questions in the exact same categories (all the body systems, solution chemistry, etc) and don't have enough time to study EVERYTHING next week. Anyways, I've done all the AAMC practice tests except for 3 and 4 already, and that's gonna be an issue if I want to see how my score is improving in the next month. Is it possible to buy Kaplan tests if you're not in the class? They seem to be the best tests besides AAMC to use but I can't find anywhere to buy them. If it's not possible to buy them, can you re-take tests? One of my friends told me she'd let me re-take her test if it was possible, but she didn't know if it was. Also, all the May dates are full, what do you guys think the chances are of some opening up in any of the cities near me? I noticed there were a couple extra spots open in my city for the Apr 16th date that weren't when I first signed up so, so I'm assuming the same will happen with May, but just seeing if anyone had experienced this already when a date didn't open? Thanks.
