hi guys i signed up for the AAMC practice MCAT online. i heard it was useful. now maybe i dont know how to use the site, but is there just ONE test available?? i took the test as a diagnostic (kind of) and then i tried to customize, but the customized test was just a mix of passages from the first test i took. so, can anyone tell me how to use the site correctly? or is there really just one test?? thanks for your help!
