TIP: Get college credits for free or almost free.
CLEP (College Level Examination Program) tests are available at most colleges. Take a test, and you can get credits in a concentration such as humanities, social sciences, etc. There are various tests out there, and at my college there were up 18 credits available via CLEP. I got 15, and on one test all I did was guess. Each test cost about $30 back in the stone age, so it was worth it even if all I did was get lucky on one of them. In the end, I got to take my senior year part-time and hae a blast.
Also, many colleges offer proficiency exams for certain courses. Check with your college's testing department or various academic departments to see what's available. The tests are usually free, so you have nothing to lose even if you were to go and just guess on the exam. At the end of my senior year, I realized I miscalculated my gen-ed credits, so I took a proficiency exam in Poly Sci 101 at the end of the year and was able to graduate in time.
You really don't have any thing to lose but some time, but you can gain college credits without spending money or time in class, thus freeing up your time and resources for other things.
