  3. Thank you Kyle for this great questions. The goal of these questions to acknowledge you and other students of the important topics of the real test. These questions are for studying and not for testing purposes. They facilitate memorizing topics that are repeated in most USMLE tests.
    Again thank you and good luck

  4. Hello Sir, these questions are really nice, but if these are real exam questions which are being repeated, how can they all have only 4 options, real exam questions have more options always, and the question length is also much bigger?
    I apologise for this query but I hope you understand my asking this as genuine.
