it's highschool WHO CARES WHAT YOUR GRADES ARE.
as long as you still graduate, you can always go fuck around some community college for 1yr to get your grades back up to go to univ. srsly. highschool is a joke, just have fun because the real work starts when you graduate.
i dropped out in Grade 10, spent 6yrs partying and touring with bands then went back for the GEd (good enough diploma), spent 1yr at a shitty college, and still got straight into the UBC science program. fuck highschool
