What Practice Test Geeks adds beyond an AI chat for MCAT

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

  • A timed, full-length MCAT mock exam — 230 questions in 375 minutes with a 50% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
  • A fixed MCAT question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
  • Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
  • A printable MCAT cheat sheet you can print or save as a PDF.
  • MCAT flashcards built from the same question bank.
