AAMC states that although tests can be, and are different, they each accurately test the "mastery" of a students ability in each of the sections. Yet, I question this due to the wide diversity within the tests. I realize I could be being misled by information, but for instance, I have heard students claim that they had A TON of a certain subject on their test ( say perhaps O-chem) while others say that they had none. I'm just curious on others thoughts about this and whether they believe the 2015 testing group is being used too much as a guinea pig group. BTW My own opinion is that the test lacked a consistent balance.
