This USMLE package includes the most important topics that we see in the real exam. You'll have all you need to practice and master the USMLE.
There are full exam-like cases that needs more thinking and time, and there are hundreds of smaller questions that go straight to the point to save your time.
The high-yield topics are commonly repeated in previous exams. These topics are covered with detailed explanation and external sources for further reading.
For optimum results, you are expected to repeat the questions as much as necessary to memorize them. You should also study topics that you frequently get wrong. By following these steps, you will have seen most of what will come in the real exam.
The exam questions will, of course, be different than the ones displayed here. However, the topics are all the same. For example: we have a question asking about the causes of pseudomembranous colitis, and the displayed answer is Clindamycin (which is the most common cause). The real exam is likely to give you a scenario with a patient taking Clindamycin and then ask about the likely complication that they might develop (like pseudomembranous colitis).
These topics are carefully selected and revised with multiple residents who all passed the USMLE with flying colors.
