Just looking for some tips/advice in this area. As I look over some review material I can't help but think "I can instantly recognize that!" But, I know it's not that easy. For example, suppose the diagnosis is giant cell tumor of bone. Are the answer choices all things that look similar to this? Or would half of the answer choices not even have giant cells? Also, did you as a general rule never look at the answer choices before looking at the slide, so as to avoid bias? Thanks for input.
