<p>Calc 3 - went to class, up to 2 hrs per week outside of class. I got through this because of what I did for physics in high school.
Linear Algebra - About 5 hrs/ week total including class / hw. (found it really boring so I did not go)
Diff q - went to class and about 4-5 hrs outside of class a week. Useful for other classes I took, just wish it went more into analysis.</p>
