Ive gained more as a student in my time here (Jan 14-Present) then I did in my undergrad from (Sept 2008-Dec 13). Some classes are more challenging then others, and yes there are some professors online who really dont care. However I believe that the you find more who do care. Nothing is perfect. I have had in class professors who don't care as well. If you apply yourself it will get noticed. The amunt of effort and time you put in, will be seen by professors and you will be rewarded for that.
