I am finishing up my BA with online classes (TN has a program where you can get your degree through one of several TN universities, using online only classes). This is my first semester, and it has been pretty rough.
I'm taking 4 classes, psychology of personality, into to public relations, social psychology, and cont. lit. There is a TON of writing and readings to do. Our weeks start on Tuesday and tests must be took by Sunday or Monday depending on the class. There are tests every week in every class except for personality.
There are discussions that you must post to every week. For instance in my lit class, we have to do 3 discussions per subject (each week more or less). All of this is VERY structured. We have to do one original discussion (be the OP) then two responses to other students topics. It isn't like here. All of them are basically essays. Your main topic would be a normal size essay, and you response would be at least several paragraphs. There is little to no chit chat.
The absolute worst part is the group projects. UGH.. you get a bunch of punks that don't want to do there part and you have to do it for them. That part sucks.
Now, all in all this semester has been rough. BUT, it is getting easier. If I had it to do over again, I would have started out with just a couple of classes and built my way up.
