I languished in my computer science degree in much the same way. I graduated with good marks but it was like pulling teeth. I questioned whether I had chosen the correct path.

Now that I'm a programmer in the real world though, I love my job and I've learned more since entering the workforce than I ever did in school. The passion has gone from 2 to 9 and the rest flows from that. Maybe you're just not wired for the college learning format - god knows I wasn't.
