Efficiently go through a set of prep books and complete discrete questions after you read a chapter. Do as many practice passages / questions as possible. Review them after and understand the rationale behind why each answer choice is incorrect / correct. Do timed practice test from a 3rd party (EK, Kaplan, Altius etc) and then take them up the day after. Review weak a topics and knowledge gaps. Rinse and repeat. Save the AAMC Practice material until ~1 month before your test date. Treat the AAMC material like gold and review their rationale behind incorrect / correct. Review weak areas and gaps in your knowledge. Try to chill the day before your test. Crush MCAT.
