3.4 (science gpa 3.8)
All night before exam which happens 3 times per quarter per class. Extra few hours every week depending on homework/quizes.
Stupid GE courses with "participation points" for attendance brought my grade down. Whatever. A lot of Cs and Bs in drawing, english, poetry, etcs which were required to graduate for my school.
Honestly I think very few people study every day.
