Yeah man, since you have some college experience it's not like you'd be missing out on learning group skills. The only disadvantage of CBT is it's lonely work, no friends involved; but that's really a damn good thing, especially at your own pace. Sometimes, your own pace can actually be faster than the in class curriculum.. saves you lots of time. Ontop of that, no driving to school (or to another class if you're dorming already).
I could think of many more reasons to take CBT after some college classes. I think it's a good idea

Good luck with it if you choose to do it.
