Greetings. I am going into grade 12, and fear of getting low marks this year. I only will do bad if I get too stressed, then I procrastinate, get really high levels of anxiety, OCD levels skyrocket. I just get bad. Even though I was stressed in grade 11 for one semester because the guidance councillor wasn't (?) able to get me into another class without dropping a subject I wanted to take (computer science, law). So I "dealt with it", ended up getting horrible handwashing OCD, several panic attacks, usually 1-3 a week (expected and unexpected), and just worn out from stress and lack of sleep. I didn't fail any courses though. Didn't do bad either, but I worked myself too hard for my brain.
Anyways, about marks, Ontario Canada for high school works in a percentage system, ranging from 0-100%. My lowest high school mark was 77% in biology (with 70s being in the "normal" range), and my highest mark was a 97%. I almost had a 98%, but dropped a percent because of exam. The biology mark was lower than normal because it was during my grade 11 first semester time (see above story), and the teacher sucked for me. She said "don't take notes" and would get students in trouble if they took notes. Bad on my part. Should have made notes. Plus, it is a memorization course, and since I have memory problems (my LD), it is a lot harder for me to memorize than the "average person". So a lot of factors went against my mark for this course.
One thing though, I did (and still do) get a lot of accommodations. Since I have ASD, LD, and anxiety disorders, I fit three of the eleven (one category is "multiple", but the person I go through doesn't want me with this category so teachers know I have these specific issues). If you are curious on this, here is a link:

The accommodations, honestly, help me be able to function and do well though.
