How much time and effort do you put into your CS, Engineering, Science, and Math studies?

You are an overachiever and brilliant. I’m just puzzled by how your motivation was merely to challenge yourself? Point noted, I will aim for a 3.3. That way a 3.0 is almost certain. I also work part-time and have very little free time. Partying is not my intention. It’s just that adding one more class per semester could mean finishing the degree in one less year. I just realized I made a mistake, Its actually linear algebra that I have to take for Computer science. Whew! I got it mixed up with differential equations. No wonder I was confused how you could spend 25 hours on a 3 unit, 2.5 hour per week course. Is one summer internship enough? Originally I planned to spend my summers taking classes. A couple hours per week studing/hw outside class for Calc I, II, Discret, as in 5 hours outside class or more so about 10 hours for the ‘typical” student ? The deadline to add classes is soon and I have been debating whether I should add a fourth class. I took stats and Pre Calc in high school. But college is more fast paced.
