Recently, I haven't been faring too well. My CNY plan? I'm kind of scrapping it. Since the 10A, I feel like I haven't gotten the hang of solving complicated AIME-level problems like before, and recently my AIME scores have been rather disappointing. I decided to spam AIMEs instead of reviewing theory, but I keep on making sillies. My mind just doesn't seem in the right condition.

For example, recently I took the 1995 AIME under full testing conditions. Midway, I ran out of gas. My computations got blurry and my mind felt so tiring. I ended up with a 5 and like 3 or 4 sillies. After mastering every question, I felt better and took the 2013 AIME I. And guess what, I got a 5 again, this time with a lot of sillies as well. Finally, yesterday my mind felt really sharp and I confidently took the 1996 AIME under full testing conditions. I felt really good when I solved 12 problems, each of which I felt had a 90+% chance of being correct. I even answered #14, for example. And guess what, I got a 6. I forgot to read the word "positive" so I was off by one. I computed the probability of an event not occurring when all I had to do was take its complement. I made a basic division error. In total, 6 of the 12 questions I sillied or misread, despite having checked every one of them before submitting. After the test, I realized I can easily solve even 2 more questions that I didn't solve during the test.

Had anyone experienced such kind of things or can share their story? I know I have the theory to get a 9 on the AIME (what I need for JMO), but it seems possible only if I adjust my brain to optimal condition. Does anyone have any advice on how to do so?

EDIT: Today, I took the 1997 AIME, and got a 10. May this mark a turning point in my recent slump? We'll see!
