What Practice Test Geeks adds beyond an AI chat for C-14

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 C-14 mock exam โ€” 50 questions in 76 minutes with a 70% 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 C-14 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.
  • C-14 flashcards built from the same question bank.
  • Free C-14 practice tests with the correct answer shown after each question.
