i'm taking the online one now. Interestingly enough when I signed up, the online was like $400 cheaper than the classroom. No real complaints about it, you get identical books/materials, lectures, online stuff, and homework you would get from the classroom course. I'm not sure how the classroom instructors are, but the ones online are pretty good on their part.
Couple things you may notice, your instructors may or may not record and email you a copy of the lectures. I think 3/5 of my tutors send us emails of the recordings. It really depends on how many students they have or how busy they are. However, the online student center provided us (though i'm not sure if it changed with the website update) with pre-recorded lectures of every class, but they're with a different instructor and may not answer any specific questions you may have
Depending on where they're teaching from, theres obviously gonna be a short delay, so no one bothers to use the mic except for the instructors. The rest of us just use the chat window and it works out pretty well.
Kinda puzzled why they jacked up the online price all of a sudden....
