I am a MS1 in my second year, and I am doing pretty well in class. But, one of the things that I really haven't been able to do is do a bunch of questions. I can just study by reading/reviewing and still do well, but I find doing questions really hammers home the content. I am saving UWorld for dedicated step 1 prep, but am wondering if it would be worth my time to do a qbank along with my classes. By the way, my curriculum is 1 1/2 yrs of basic sciences and it is systems-based. I am leaning towards Rx and am wondering if it can be done system by system.
