Ask HN: What would you do?

I'm a (first semester) junior studying Computer Science. I took last semester off to work with Lift (funded by &#38; partners with The Obvious Corporation), and that was an amazing experience. I figured since I was halfway done with school and this much invested, that I would return back and finish up my degree.<p>And then I started taking Calc II.<p>I've been to tutoring 3 times/week for the last 2 weeks, worked through more than the assigned homework questions, and visited my prof for help, but I'm just not getting it. By not getting it, I mean I failed the first two quizzes and recently got below a 40% on our first test.<p>Unfortunately, this is the 4th to last math class I'd have to take if I wanted to get my degree in CS. So, I've been thinking about changing to Entrepreneurship with a minor in CS, or re-taking Calc I this summer to prepare me more for Calc II (although that would push back my graduation date... and cost much more).<p>I'm interested in hearing if any of you have had similar experiences, or any thoughts on how I should go about this?<p>I ask because what got me the job with Lift (and a job this summer with Rdio) were my side projects. With how heavily math-based our CS curriculum is, I'm worried I won't have any time to put into side projects and still get above a C- ("passing grade") in all of my classes.<p>I would appreciate any help whatsoever - thoughts, comments, concerns, etc. My contact info is in my profile, but I'd love a discussion to be started here, so others that may be going through the same thing can learn from this as well.<p>Thanks, HN.
