You're talking straight out of your ass, buddy.
Obviously you didn't get my form, otherwise you wouldn't be saying ignorant **** like this.
ALL TESTS ARE NOT MADE EQUAL.
According to your hypothesis, if I were given the option to do a double integral versus a simple algebra problem, I would think them both "easy" because I know how to do them. No, not necessarily. What makes something easy if it is familiar, conceptually simple, and relatively easy to process in a certain amount of allotted time. You might know how to do something, but if it takes an hour to solve a problem, it's just not worth it. In that case, would you still say it's easy?
Boy...you are something else. One of those claim-to-know it all types, I see.
It's not possible to prepare for every question on a standardized exam. They don't test you on specific questions here. It is not a regular test. That's the main point.
If you really did think it possible to be familiar with every type of question (in that case, you should be able to get them all right), then why does the AAMC claim that the scores of test takers should be roughly the same, whether or not the exam was taken in April or August, or whether you got Form A, B, C, D, or XYZ.
You have no clue...
P.S. You fail to realize that 99% of the people on SDN taking the MCAT have attempted to thoroughly prepare for the exam. Do you not think we would be "intelligent" enough to know that we should prepare for every topic that may be covered? I know I went through every damn thing...
