Classes

I began my Core Java class last night and, well, I must admit to being a trifle disappointed. The instructor is an affable enough fellow, but I didn't feel that he gave the material enough explanation. I worry that if I hadn't already familiarized myself with some of the Java fundamentals that perhaps I would have no idea what he was doing. Or maybe I just prefer having more in-depth explanations of concepts that don't necessarily require them?
Anyway, the class went reasonably well, I suppose, but I don't think it's going to give me what I need to get a certification, so it looks like I'm going back to studying more on my own as well as taking the class. And I still have almost half of my Christmas knitting to finish up. The feather and fan scarf/wrap I'm working on is just not seeming to grow at a rate I find acceptable, so instead of working at it more diligently, I become frustrated and set it aside. Foolish, non?
