I’m trying to graduate in the spring of 2018, but I only have 6 classes left, so I can go and continue my education. All of the classes are 3 credit hours. The classes are: 3D Design, Color Theory, Art History 2, Art Appreciation, Intro to Psychology, and Stats
Six courses is a lot but if you are a semester away from graduating you should know best what kind of courseload you can handle. Another option might be ti finish up in the summer.
Unless you have abnormally hard professors, Art Appreciation, Intro to Psych, and Stats (if introductory) shouldn’t be too bad. You could check to see if you could take one of those three online or on-campus during the intersession (usually 2 or 3 weeks).
If you are prepared to have little free time (but remember, only for 15 weeks of your life) it seems doable. You will be busy.
I did the same thing once, and only once. It was brutal but I survived it. How are your grades up to now, and are these courses in subjects where you feel strong?
Another option is take one of those over the winter mini-mester if you have one of those.
If you are generally doing well, you could do this. It will be tough and you have to keep up with reading/homework.
