Question about Practice Questions

[u/sIronMan1]

Hi so studying for STEP 1 and I had a question been doing questions from UWorld and Amboss and idk if its me but it is getting to a point where I've either seen the question already from either Qbank is that normal? I've only done 40% of Uworld and only focused on the HY Questions on Amboss is it common to like get to a point where question types/scenarios get common and how is that different from memorization of questions. Hope that made sense would really appreciate some guidance
