I took the Kaplan online version of the course and thought it was great. With the classroom course you have an instructor you can ask questions to and get advice from. With the online course, you can do the course on your own time when it is convenient for you. I was working full time so the online course was perfect for me.
Also, it looks like the kaplan class (either online or classroom) is a $100 off if you sign up during December online -->
