If that GPA is from high school, then you need to find a program (local or otherwise) where you can take remedial math, English, US government, and biology (the basics) and get your GPA up and reapply.

If you earned the 1.2 through a college experience, then again, you’re just going to have to do correspondence, online, or something to get your GPA up.

I don’t know what IL laws are regarding CC’s obligation to accept you (I googled the college you mentioned), so I dont know if you can sue them, but if they are obligated to take you, I suppose a law suit could be a last resort.

All this, assuming that you didn’t threaten the safety of the staff that would cause security to remove you from the premises. Anyway, if you are serious about this, you’ll find a way to work it out. Good Luck.
