How does one know how many hours to take?
It depends on the courses. Not all credit hours are created equal, and anyone who has graduated and taken a few tough classes can tell you that. After all, 4 units of English 101 is infinitely easier than 4 units of Organic Chemistry or Quantum Field Theory.
Worse yet, labs are often worth only 1 unit by end up requiring just as much time as many 3 unit lecture courses. If your degree has any labs at all, keep that in mind.
All you need to know is that there is a minimum number of units for full-time enrollment, but that value depends on your university. And certain scholarships may require more than the minimum number of units. Beyond that, take however many courses that you feel comfortable with. Don't worry about the unit number so long as you're over the minimum.
I did a Physics BS with a Math minor in 4 years (5 average) with the following load (full-time status is 24 per year). I think I had a pretty easy 4 years, all things considered; actually, I had finished all of the degree requirements by the end of Fall semester my Senior year, but why let a semester of scholarship go to waste? Senior year is the time for fun courses!
Summer before college - 3 units by correspondence
Freshman - 17 units/14 units
Summer after freshman - 4 units by correspondence
Sophomore - 16 units/12 units
Summer after sophomore - 3 units
Junior - 12 units/14 units
Senior - 14 units/9 units
ALSO, investigate correspondence courses at your university! If you're the type who has any proficiency at all in self-learning, these courses are for you! At my university it was 9 months for completion or 12 months if you pay an extra $50. I believe the cost per credit was half of the normal price, since there is no lecture hall. Both times I ended up learning much more than my peers taking the courses in lectures. Take Differential Equations by correspondence, I swear you'll thank me later. All you need is the book and the professor's e-mail for questions. Learning at your own pace is infinitely better.
