So I'm like a 8th grader so almost 9th over the summer and I suck at AMC 10. I got like a 75 for my first time but I can do like almost all the problems from AMC 8 with enough time which I find really weird because most other ppl who can do that get higher AMC 10 scores. I do like the first 11 problems a day from past years to try to at least get down the first 10 questions and move on from there. Does anyone have any good suggestions on how I can boost my AMC 10 scores?
+ something annoying that often happens is like I don't even know where to start when I see a problem.
