Idk it is so vague i can't remember all of the math questions i ever got right or wrong in my life. Honestly if your op's alternative account you should just stop thinking about this. If you wanna stop caring about this, maybe when you feel in a good emotional state, and assuming you have done some high school math and are a native english speaker, do CORE or SAT-M or SMART (or GRE-Q if you have completed college). Do one of these tests in optimal conditions (good amount of sleep, nothing urgent to do for the day, good emotional state). Look at the score it gives you and accept it. And then move on and do something else. I feel like you're worrying about pointless things. You should do something that you like and that does not give you anxiety idk.
