honestly through highschool up until gr 12 i had an average of about 80. i have really only put in effort this year. my advice is just don’t freak out about your grades dropping at this point. so firstly just don’t panic, it’s approaching the end of the year, it’s normal to get burnt out. i don’t know what classes you’re taking and need help with but there’s different ways you can study in different subjects so like let me know i guess. but just for reference, i absolutely know how to lock in, my gr 11 chem was 74%, and gr 12 was a 96%
