does a 75% on the usmlerx really correlate to a score above 275 on the step 1? i have a hard time believing that. i've been consistently getting 75-85% on my usmlerx practice exams and the predictor comes out to "score above 275". i feel that the questions on usmlerx are easy, hence a score of 95%+ should correlate to a score above 275. i feel that a 75-85% score would correlate to a 235-245. anyone else feel the same way? or am i just being hard on myself?
