The answer lies within our vision, which is to make top-quality medical education available to as many students as possible. We know that in order to become a great doctor, you should have as much experience with clinical case questions as you can — not only do such questions deepen your understanding of important medical topics , but you will also learn from the beginning with the type of questions you will face during your Step 1 and Step 2 exams.
