it all depends on how you learn, if ur taking a class for something you have to memorize a lot, i would suggest an online class, its much more relaxed and on ur own time. unless you know the teacher and he/she is really good. for english, psychology etc. i woulds suggest in-class. I am currently taking a medical terminology class online, and I know if i didnt take it online, I would have probably have a much lower grade. In general Online classes are much more self paced.
