Here's some good advice for avoiding "academic hell" in college. The gist of it is this:
Many students believe that taking a punishing course load will somehow indicate a higher ability; making it easier to land jobs or post-graduate positions. Here’s the reality: it won’t.
. . .
Employers and professional schools will notice your GPA, where you went to school, and your major. They don’t care about about how many credit hours you jammed into each semester or how hard your schedule was compared to others in the same major. The same goes for graduate schools. Though it’s true that specific professors on the admissions committee might look at your grades in the classes relevant to their specialty, they don’t care about the general hardness of your particular schedule [the way college-admissions people do].
. . .
If I was only allowed to offer you one piece of advice to make your college years easier, it might be this simple rule. Nothing seems to have as profound an effect on student stress than a killer course load (though a killer extracurricular load runs a close second). What pains me is that this stress is so unnecessary. Get the credit hours required to graduate. Take the courses required for your major. That’s all that matters. Don’t make you life much more difficult than it needs to be.
