I don't know how it is in the US but in Australia my CS results meant bugger all after I left college. The majority of companies care far more about you doing your own personal projects and having a passion for what you than the grades you got in college. So keeping this in mind, work on your startup as much as you can while passing your courses and you'll come out far ahead of others who get A's but don't have a single personal project or demo on their resume.
