Agree with the other answer about taking a diagnostic to start but I think the frequency you should take practice tears after that totally depends on when your test date is scheduled for. MCAT study plans are highly individualized based on what you need to do to improve your score and your timeline. If you provide more info on your test date/how much time you have to study and what areas you’re struggling with (specific content, timing, approaching questions, etc) I can give you a better answer for you!

Hi!
I would recommend you first take a baseline MCAT diagnostic exam before you start your studying. This can help you or you and your tutor create a study schedule that is targeted and specific to you!
Once you begin studying I would recommend taking practice exams after 3 weeks, and then every 2 weeks, and then one per week for the 2-3 weeks leading up to the exam.
I hope this helps and let me know if you would like to discuss further!

Just take one practice MCAT to get a sense for format - then wait until you have done your other practice material and content review!
