USMLERx has already been battle-tested by thousands of users. Here's what people are saying:

• "I used USMLERx and thought it was incredible... I scored 99 on the exam, which I largely attribute to the First Aid book and USMLERx. Keep up the good work!!"
• "Wow... USMLERx is badass... USMLERx was challenging and required secondary and tertiary analysis (2-step or 3-step thinking)... this is more representative of what the real test is like."
• "I own Kaplan Qbank as well and completed most of it... but I heard so many good things about USMLERx that I just bought this and I love it! The explanations you provide are awesome compared to Kaplan Qbank."
