None - the only difference is that it is one on one so it feels like that to the user. Education in a lot of places is broken because of class size.

He could be right. It might feel that way due to time management and how long email correspondence takes to answer a questions.

I used it at the end of my college algebra class last semester. It was definitely better than the book/webassign and the supplemental math class I had to go to for the class. I ended up using it to finish a essay on endosymbiotic theory for bio and on my last couple math assignments and the exams. I got over 90% on all of them and I didn't "cheat."

Overall as a tool, it will make my life allot easier. The fact that I won't have to learn a knew platform every semester for math will speed up the learning process in itself.

We'll see, I start class again on Monday. I'll be using it for precalc, chemistry 1 and medical ethics. I predict I'll get straight A's and have more time to self study due to it improving my work flow.
