My grades are naturally high, so I've never had to revise. I'm in Y8 now, and I'm starting to try and get into the habit of revising, so that when I do my gcses I'll know how to, but my test score averages have started to drop from 95-100 to 85-95, so I'm really worried and I can never concentrate in classes or when I'm trying to do revision even when I really try. People started to think that I revise in 'secret' but tell everyone that I don't to make them feel bad, which isn't true at all! Last week I got an 88% in Physics so I got really upset and angry at myself and everyone just got kind of annoyed and said that I'm being dramatic, when I just have higher expectations.
Does anyone know any tips to help concentrate when doing revision and to not make it boring?
