|1.||answer key score|
Getting 100% on a test, quiz, etc.
Best to avoid saying this in front of teachers as they may end up thinking you actually cheated with an answer key.
Can also be said "answer key marks/test score/score". Or just "answer key".
"Holy shit! You got an answer key score on that math final?! Why didn't you help me study?!"
"I did, you tard, leave me alone."
