Columbus Hondros students...opinions on teachers?

Well, had my first week of class last week and I can honestly say I'm worried. I never thought that going back to school would be easy, and especially not for something as serious as nursing.
I find only one of my teachers does a good job of presenting material and making it fun and easy to comprehend. The others...not so much. There was a lot of material presented and I spent the weekend studying and trying to finish homework. I know it is going to be hard to do the program, but I hope I didn't make a mistake in choosing my school. I have been to college before but I can see how easy it would be to drown in these classes. Anyone else feel this way?
