Dude, I feel you on this one.
This semester I only have masteringbiology.com and my professor doesnt use it much.
Last semester, my chem professor was DEVELOPING a fucking online book/homework site and we had to use it.
I had a calc class that had online HW too, it was so annoying putting the equations in.
In both calc and chem, I felt like the online aspect got in the way of me learning anything through the homework. Entering an answer and having it be wrong because something wasn't in the right format really pissed me off. Chem was even more outrageous, and I am confident that if we worked on paper like normal students, I would have done better.
Will the real world require you to deal with the struggle that online HW presents?
Will the final be online?
No- so we shouldn't have to put up with this bullshit.
