@FionaDoctortoHopefullyBe don't let non-AAMC practice exams deter you. Those have no basis or validity when it comes to determining where you stand. Use AAMC Sample Test, Exam 1, and Exam 2 and average those scores. The average of those scores will give a better indication of what you may score on test day. If you are happy with that score, take the exam. If not, keep studying!
