I have kaplan 84%, Rx 83%, and Uworld 84% but my baseline NBME (13 taken at 5 weeks out, after kaplan and Rx but before Uworld) was a 232, which shocked me cause I thought, seeing everyone elses scores on here I'd have done a lot higher. I've never touched Zanki. I wonder if thats that why while going through Uworld, I would randomly miss questions that I thought were impossible and for sure would be a <30% correct type of question, only to see like 60+% of people got it correct lmao I had no idea zanki gave away Uworld answers like that cause I've never seen/touched it.
