In first year, my grades were better than all 4 years of highschool. The weird thing is that in highschool, I've never skipped a class and in first year, I barely went to class. (It's funny how you'd wake up for school at 8:30 but you wouldn't wake up for lecture at the same time even when you lived on campus.)
That being said, I hate how we had little room to maneuver in HS . (Almost every course we took were required.) I know the point was to get us exposed to a wide variety of courses, but I still hated some of the subjects we had to take. With each passing year of HS-and therefore more choices- my grades went up.
Also, at my HS, we were warned over and over and over again that university was no walk in the park. We kept hearing these horrible stories about grades dropping and being on probation.
I remember a story that my geography teacher told us about her friend who had to repeat a course because of a silly mistake on her final exam. The exam had consisted of 100 MC, and by accident she had missed the 3rd question and instead bubbled her 4th answer into the 3rd spot. Hence, every answer had shifted and she ended up getting 33/100 just by pure chance. Since scantron answers were final at the time, there was nothing she could do.
There were also stories my math teacher told us about never being able to finish an exam and always having to pick questions that were worth the most and was doable. Then he'd leave the rest to bellcurve.
Anyways, the point is, I was scared
