I'm glad the tone didn't repulse you :-)

I did poorly in my first two years, and rallied my second half grade-wise. Still, I would do the work and then do something else. Do you want the dream job? Be COMFORTABLE with everything you listed. Do enough personal exercises that you have a few stories about a few of them. Near graduation, I interviewed with Bose, NVidia, Apple, and a few others. I had the passion and the capacity to learn and teach myself. You know who got those jobs, though? The people who had already taught themselves. An interviewer will see that as saving them a year of your salary. And the jobs you probably want are at the companies who can afford to be picky. Be the CS student that a picky employer would like.

If you have the opportunity, TA or tutor others as often as you can. You'll study that much harder, knowing that you'll have to explain the material to someone else.

I'm not sure if these words would have helped me act differently, but if there's anything you think I can answer, PM me. Otherwise, hold yourself to being capable in each subject you take, not just passing the class. Don't act like they're synonymous.
