Hi Guys, While there are a lot of discussions about the pros and cons of USMLE Rx vs other question banks, I haven't been able to find much info in the archives about how people are actually doing with USMLERx, and how it correlates with scores overall. Has anyone used the score estimator formula that USMLERx provides? (% x 2.64)+47= estimated score. How close was it to actual performance/NBME scores? I'll share my experience: before studying, took NBME 1, got 192 Began using USMLERx, was getting 45-55% correct one week of studying, took NBME 2, got 198 two weeks of studying, USMLERx about 60-65% correct took NBME 4, got 208 three weeks of studying, USMLE Rx is at about 73% correct: I'm going to take another NBME this weekend. Seventy-three % with USMLE Rx is a 240, but I am 100% sure I'm not anywhere near there yet. I have 2 more weeks to go. I'm actually pretty happy with Rx, but if people think that it's not a good predictor of the final outcome, I might throw the towel in and get USMLE World. I know pretty much everyone who has an opinion favors World, but I'm poor.
