Hi, do you guys recommend that I do uworld twice? I am going over uworld for a second time but I don't know if I am doing the right thing. When I go over questions I make sure that I understand the concept. But there are some questions where I just know the answer to because I didn't know that one fact when I first took uworld. I don't know if I am wasting my time or I should just start a new question bank. I tried doing 20 questions from the kaplan q bank and they were so difficult. I don't know if I am just remembering the questions or I am actually getting the concept. any advice? thanks
