@Loandrob2014: I’ll tell you my (short) story and tell you what worked for me, what didn’t, and what I regret, and the advice I have for you.
I was 23 when I went back to college. I was working full time and taking 1 class at community college (1 class every semester, this meant 3 classes as I took the accelerated summer classes as well).
I decided to quit my job and finish school full time and I would be finished in 2 years, if I continued to take summer classes.
What worked for me:
I saved loads of money by taking online classes at community college first. Online works for me, it’s not for everyone, but I love it. These classes cost me $80 per credit while my classes at Penn State cost roughly $500 per credit. The savings was substantial, and all of my credits transferred. If you do this make sure your credits transfer first.
What I would have changed:
I wish I kept my full time job because I miss making money. I hated my job and just wanted out, but now I hate being broke, and I have to consider it as part of my expenses. Yes, the degree itself cost $X, but I lost out on $Y by quitting my job. I could have easily done 3 classes per semester while working full time. It would have taken longer, but I definitely regret leaving my job.
What I recommend for you:
Self study, hire a tutor, anything, but re-take your entrance exams so you can skip some of those math classes. I had to start all over again (Pre-Calc in HS but had to start at Algebra 1 in college). That was 4 math classes to graduate. I could have retaken my test, and best case scenario, I would have only needed 1 class. 3 classes would have shaved my first year of school, considering I took 1 class at a time that first year, which were all those math classes.
I recommend summer classes. They are easier and faster (usually 8 weeks compared to 14 weeks for spring/fall).
You said you go for it, and then change your mind. Guess what- You can just take one class and see how it goes. Don’t waste your own time. One class will take up 6 hours of your time per week (3 hours in class, 3 hours doing HW/studying). If you decide it’s not for you, whatever, you are now more educated and learned more about yourself in the process. But guess what- You will want to take more classes and you will want to finish your degree because it’s what you want! You can do it!!
