Cleaned up the code, removed some dumb comments, added new ones, cleaned up language in some places. Added the clear grade button to the course info view controller. I have decided rather than having buttons for assuming grades and curves it is easier and more intuitive just to give the user the ability to clear grades and curves... All that is left to do now is add a curve button and the associated functionality, the clear curve button and functionality, and probably an exit button to the course info view controller. VERY close to done now. Should be finished up with version 2 tomorrow.
Removed all tabs again
