you still have to do the course work and it's fucking hard online..there's higher bar.
i started a course online at my school because it was an off day to my schedule (i didn't want to be there 5 days/week) i ended up dropping because it was a lot of work. ended up taking the same course in person next semester..best decision..didn't do shit except show up and got a "B".
many top florida schools now offer curriculum to full degrees online including UF.
No its not harder there is just less interactive discussion - you lose the in person "sounding board", which most students are not used to these days. We are social creatures.
