Gold Standard MCAT started 25 years ago when Brett Ferdinand began writing an MCAT prep textbook while enrolled in medical school. This book has since expanded to online courses which include practice tests and videos.
Gold Standard MCAT prep offers their own online subscription MCAT prep courses as well as home study options utilizing popular commercial MCAT prep book sets. Their approach to the home-study courses is a bit unique, as they offer you a choice of one of the following commercial MCAT prep book sets: Kaplan, The Princeton Review, or Examkrackers. They offer 20 full-length MCAT practice tests, which can be purchased on their website, as well as 1 free practice test.
