Sometimes I feel completely overwhelmed.

This past year has been a rough one for me. A lot has changed, seeing as I'm coming to the end of my formal schooling (Australia), and the big exams are coming up soon next year. I used to be one of those kids in school who could fly straight through most tests, and come out with Bs and As on the report card. However, school has been getting harder and harder and my marks are starting to reflect it. My marks are not that great anymore, especially in maths, and I'm losing faith in myself. Anyone else feeling like this? I know I can push through it, but I don't know if I'll get the mark I know I could get. Hope I could get some insight from you guys.

Same thing happened to me but I was lazy af. But fact is school system is fucked up, they want you to be great at everything, but then how will you have some time for yourself, and learn something that you are actually into? Personally I don't care about grades anymore, just want to pass while I am learning stuff I like.

I'm already overwhelmed by sleeping. This is too exhausting.
