I'm in year 10 and lately, I've been feeling really demotivated about my GCSEs. I'm predicted a few 7s, mostly 8s and some 9s at the end of year 11 and I feel like I'm going to end up getting mediocre grades. I started my GCSEs (9-1 new grading scheme) in year 9 and I used to get 6s, 7s and 8s in tests, but now that I've started year 10, I'm getting 3s, 4s and 5s. I'm really bad at time management and can't really find the revision techniques that work for me and even though I try working hard, I never feel prepared before tests. I've got mocks coming up and I'm really stressed about the grades I'm going to get. I'm also doing my English lit and Latin exams at the end of year 10 and I really want to get 8s, but I sometimes feel like I'm not even going to pass them lol! I do have a really low self-esteem, in case you haven't noticed.Does anybody have any advice on what I should do?
