The next thing to consider is the course type, as MCAT prep courses are offered in multiple formats, i.e. regular, classroom-style lecture sessions, one on one coaching, online, and even self-practiced courses.
You also need to make sure to check if your course provider is giving you a clear guideline on utilizing the best of the course materials and other study tools often offered by the institutes.
Taking this into consideration, it’s a good idea to check out the number of practice questions that particular course includes that you are going to sign up.
It’s also a good idea to make sure that the prep course will offer you access to the AAMC official practice exams for the MCAT.
