I've looked and found that it is thought that AAMC reuses questions in their MCATs, but how much variation is there from one test to the next? I mean if someone takes a test on Aug 14 and then someone else takes the test on Aug 21st will it be a 100% completely different test or will the basic outline be the same for the entire season (such as 1-2 questions on Sn2 reactions, 4 questions on enzymes) but they pull the questions from a huge question bank so each individual test resembles recent tests in terms of content but the specific questions are completely different? Maybe another way to say it is will the test follow a pattern (ie 64.5 percent Bio with heavy emphasis on enzymes and 35.5? Orgo with a heavy emphasis on whatever category) each test in a given year or is it truly random from one test date to the next and you may receive a test loaded with Bio and almost no Orgo this time and a week later Orgo is 40%+ ?
