On the Kaplan full-lengths, you can miss several and still get a 15 on something like physical sciences. But on the AAMC (say test 8), if you miss several you are down two points. So basically on the AAMC I have to be extremely accurate on it or else my score is going to be much lower than what I've been getting on the Kaplan full-length practice exams, because the scale looks harder on the AAMC, is that right?
