Hi, could anyone tell me realistically how much of an actual difference in questions answered correctly on average corresponds to a difference in score on the usmle step 3? Like if I get a 199 on a usmle world self assessment, how many questions am I answering incorrectly (per block on avg) compared to someone who scored a 230? I realize that a lot of people may not really know the answer to this question. But if you have some idea, please help because that would help me reach my target scores by figuring out how many more questions I have to answer correctly for each block. I have two weeks prior to my exam date. Thanks so much!
