Because our team of authors and editors is constantly combing Firecracker's questions and content for accuracy and clarity, our total number of questions fluctuates. The Medical/USMLE (+COMLEX) program includes about 2,300 topics with over 31,000 recall questions and 2,300 boards-style questions. Mark a topic for review to unlock the questions associated with that topic. All of Firecracker's content and questions are originally authored, so our materials will not overlap with any other resources you may be using.
