What is 90% correct on MCAT?

Getting 90% correct on the MCAT isn't a fixed score but roughly translates to a high 120s to low 130s per section, placing you in the 90th percentile (around 515 total score), making you a very strong candidate, though scores vary by section difficulty and question weighting, with 5-10 wrong often being a 128-130 range in practice tests. A 90% accuracy means around 5-10 wrong answers out of ~53 questions in a section, but precise conversions depend on the test's equating. 

What is the 20 20 20 rule for memorizing?

Memory experts recommend the 20-20-20 rule, which prescribes going over the details of a presentation for 20 minutes, then repeating the same material twice more. If material is not repeated within 30 minutes, it is not encoded into long-term memory.

Is 2 months enough to study for MCAT?

Yes, 2 months can be enough for the MCAT, but it's very challenging and depends heavily on your starting point, dedication (aim for 200-300+ total hours), and a highly structured, intensive study plan focusing heavily on practice tests and targeted content review, especially if you've recently taken your pre-med courses and remember the material well. For many, 3-6 months is more common, so 2 months requires extreme focus, good foundational knowledge, and avoiding burnout. 

Do you need to memorize the 20 amino acids for MCAT?

What is the 32 hour rule in medical school?

The "32-hour rule" in medical school admissions refers to a policy where some medical schools focus on an applicant's GPA from their most recent 32 credit hours, often in post-baccalaureate coursework, to evaluate academic strength, giving a chance to those with a weaker overall undergraduate record but strong recent performance, like at LSU-New Orleans and Wayne State. It's a way for schools to see recent academic growth, with examples including focusing on recent semesters or post-bacc programs to demonstrate improvement.
 

What is the 2 7 30 rule for memory?

The 2-7-30 rule for memory is a spaced repetition technique that boosts retention by scheduling reviews of new information on specific days: 2 days, 7 days, and 30 days after the initial learning session, moving knowledge from short-term to long-term memory by fighting the brain's natural forgetting curve. This method involves active recall during reviews (quizzing yourself, summarizing) to solidify learning, based on principles from psychologist Hermann Ebbinghaus. 

What is a top 1% MCAT score?
