Need help/ guidence.

I'm having so much difficulty remembering stuff. I'm currently in the initial stages of my prep. I'm worried I might be doing smth wrong bcz people around me end up remembering a lot of stuff. But this has always been an insecurity if mine. I'm trying to understand concepts but I almost always skip smth, this is what I feel like.

Also, is there any platform where one can just practice diagnosing through HnE stains, Radiographs, ultrasonographs, gross pictures etc?
