My exam will be next year on the 14th of January. I just started using Uworld and I have 1815 questions left to do. Currently, I am 86th in rank and it says that my median score is 48th. On most of my Qbanks, I normally get a score of 64 and above. I am not sure if this is good a score. I don't really understand. Should I move my exam or take it on the date I scheduled?
