I have about 2 weeks left until my exam. I want to take one more practice test but I am not sure as to whether I should take my second USMLEworld one or if I should take another NBME. I have only taken a couple NBME's and one USMLEworld exam. What would you people recommend? I've heard the USMLEworld exams inflate the grades alot with curves (I know I did alot better on my first World exam than my first NBME), but at the same time the NBME doesn't provide as much in depth feedback to the ones you got wrong. Still, I'm leaning towards the NBME because I heard it's a better predictor of your score, and might help me figure out which subjects to "hammer home" in the last several days. Any ideas/experiences would be much appreciated!
