In high school, my homework never used to take me more than 2 hours per day, on average. Now that I am in university, I've increased the time I spend on problem sets+ assigned readings to 6 hours per day and I'm just struggling to keep up especially due to the fact that problems are more thought provoking (proof-y problem sets for math classes) and 100 problems are assigned weekly in each math class I'm taking, while the problem sets in my other science classes are tame but I still spend time doing the recommended problems. Is this normal for a first year science and math student, or am I doing something wrong? How did you deal with the workload in first year without falling behind? I would appreciate some tips.
