Senioritis

How low can my grades drop before they take away my college admission?  I had a 3.95 average up until now but I think i might be getting a few B's this last semester..

I had a couple Fs in my last semester, just stopped going to the classes but it was to late to drop them. Grades don't really matter, got my first job because the people were more impressed with my senior design project.

Indeed, unless you want to work in academics, you want to use your college's internship program to help you with getting into the job world.  It would be weird for a company to care what marks you got.
