I have been thinking about taking a few classes at a local university. Since they are very costly, I am left wondering if enrolling in such a thing is worth it. Did any of you attend a clas of the sort? I've read that Stephen King thinks they are overrated, but then again he also believes that most books on writing are worthless. What are your thoughts on the subject? I feel confused as there are so many things I want to improve and I can't tackle them all at once (I wanna buy a good grammar too but can't decide which one would be the most useful.).
