As I am starting to prepare for my first shelf exam, I was wondering if any M4s had any advice for using only AMBOSS questions and not UWorld questions for shelf prep? I know that almost everyone uses UWorld and many people add on AMBOSS, but I would love to only use AMBOSS and not have to purchase UWorld. It makes me nervous to not purchase UWorld because everyone swears by it, but I also have really liked AMBOSS for the first two years of medical school, and if it is sufficient to do well for shelf exams then it would be great to not purchase UWorld! The only critique I have heard of AMBOSS questions is that sometimes they can be more "nitpicky" and throw in a ton of red herrings so they can be more difficult than the UWorld questions and even the shelf questions. However, as I have not taken a shelf exam yet I am not sure if this is true. I would appreciate any advice! Thanks!
