I've just applied to their program, but took chemistry and physics at the extension school this fall. The chemistry class is great- very well structured, lots of resources, and very organized. The physics class is pretty terrible, mostly because the professor is so bad- for the spring semester my friends and I had decided to take turns going to class. I can't comment on the advising or how they handle the application process as I've been relying on my undergrad institution for those services. If you have any more questions about it, I'll do my best to answer them!
