-_-. don't worry, highschool you get to have a calculator and keep a formula card. also if forgot to mention. in 11th grade you also have to do geometric proofs where there are over 30 rules to it. also I'm in the 11th grade. but I don't have to worry 'cause I am allowed to keep a list of the rules with me for the tests, I don't have to memorize all of them
