I don't stress about anything and don't study, I understand the material if I pay attention even slightly so I don't mind tests? Unless it's history... And parts of English :/ but I'm great with math!?
I just graduated so no more exams for a couple yrs but I used to just throw on some wordless music and copy all of my notes again twice. Writing everything down again made it stick for me more. Sometimes if I'd be up all night I'd also bake
B4 my exams i eat chocolate N sometimes peanut then i bully my relatives n it all goes well ┌( ಠ_ಠ)┘
