Students can determine the optimal MCAT study length by first assessing their baseline knowledge through diagnostic tests, identifying strong and weak subjects, and estimating how much time is needed to review content and practice questions thoroughly. A typical prep period ranges from 3 to 6 months, but it should be adjusted based on individual needs. To maximize learning efficiency without burnout, students can use active recall, spaced repetition, and focused practice sessions with scheduled breaks. Mixing subjects, setting realistic daily goals, and periodically reviewing progress also help maintain momentum while avoiding fatigue.
