Self-study
I think it would be helpful if there were a feature that told us which lesson to review based on our top priorities. For example, let's say next to my top priority question type to review, it would suggest I review a specific lesson.
pomodoro method might help! theres an app thats called focustown that is essentially a pomodoro studying timer except you have a character and your character is sitting down and studying with people all over the world. I saw this on tiktok and it did help with the pomodoro method. also its good to have something to fidget with. im not sure if you applied for accomodations, but you should definitely get that figured out if you want to take the test again in september or october. studious environments definitely work too; another commenter mentioned the library and a coffee shop but i feel like a coffee shop can be kind of loud at times so a library or maybe even if you're still in school to study at school too (if possible). you can also try to chew gum with flavor to fidget as well; tasty drinks like soda to give your brain dopamine; or maybe even different colored pens. there's an AuDHD activist on instagram who also gives tips and tricks for people with adhd for studying as well. her name is alora young @aloraofficielle on instagram. you might want to check some her content out. good luck! i understand the struggle too well.
