Yes, it may be hard to believe, but we recently made all of our Qbank questions available for free. Why, you might ask, would we do this? The answer lies within our vision, which is to make top-quality medical education available to as many students as possible. High quality Qbanks generally cost between $50 and $100 per month, which most students are not able to afford. 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. That’s why we decided that all Lecturios can answer all of our USMLE-style questions for free.
That’s awesome, right? So, spread the word about this incredible opportunity – tell your friends about it, and together you’ll become fluent in medical concepts with Lecturio!
