They're both fine, and there is no such thing as "more representative" of the real thing. Pick whichever one gives you a better deal! I used Altius because they were running a deal last year, but I've also heard only good things about Blueprint. No third party gives you an accurate picture of where you are score wise, but they all are fine for practice with both timing and content (except for CARS).Hello! I'm planning on purchasing 3rd party practice exams from either Altius or BluePrint. Any recommendations as to which one I should use? Is one more representative of the actual AAMC than the other, does one have better explanations?
