LOL... I agree with the earlier posts... just take a deep breath. However, since I was getting help this time of year last year, I suppose I should try to help where I can. 🙂
I haven't seen the AAMC answer sheet, but I imagine it's pretty close. I have seen the Kaplan answer sheet and the answer blocks are smaller than the real thing since the whole test is on one page - you will have separate answer sheets for each section on the real test. (the answer sheets for the 15-question Kaplan mini-tests in the review books are almost identical to the real thing). The "real" MCAT answer sheet is 8.5" x 11" and has answer blocks for 77 questions so there's plenty of room. The color of each answer sheet will be different for each section. You have a choice of A, B, C, D, or E for each question and the answer "bubbles" are ovals that are not difficult to mark. Make sure you bring #2 wooden pencils - DO NOT use a mechanical pencil - some testing centers won't catch this, and I have heard credible stories of likely scoring errors from mechanical pencils. You will not be allowed scratch paper for anything, including verbal, but you can do whatever you like to your test booklet. There is enough "white space" on each page to scratch notes or to do calculations - or you can use the inside covers of your test booklet if you really need room.
Hope that was some small help!
