Uworld qbank first pass: 81% (untimed tutor mode, random)
Real deal step 1: 261 (may 4th)
Side note:
I scored a 28 on the ACT and a 507 on the MCAT
The Step 1 is a different exam, it is not passage based and excellent reading comprehension and vocabulary will not carry your score
You have to know your content and be able to reason scientifically. I have always underperformed on standardized exams due to classical literature passages, etc. but the medical licensing exam is about the science and medicine and if you study smart and early, you can crush this test.
