I feel similar. My first collegiate math class, the teacher came in and asked the class, "do you know how to get an A in this class, two hours of math homework a night". I followed this advice and bam, A. Despite the fact that this math class was much harder than anything I did in high school and I was always a B+ math student. The next semester I followed this advice again but let myself slip a few weeks and bam B+. The next semester I strictly spent the time again, bam, A. Through upper class years my diligence in school was consistent but I sometimes had to focus on programming over math. I noticed a near perfect correlation between the time I spent on out of class work and my performance.
