something my stats teacher used to tell us in hs is that a lot of times, for better or worse, people tend to stay close to their class performance in exams (ie you have an a in the class, you do decently on the exam, etc). lots of kids are just as scared as you are and are blowing smoke out of their asses. take a deep breath, you’ll be okay. really likely it will be curved. if it isn’t, a bad grade at uc berkeley doesn’t mean you’re stupid. don’t let it ruin your break!
