I cant finish my a level!

Basically, I'm kind of panicking.
I moved to a school which doesn't teach the same Computer Science course as my prior.

I've searched for so many exam centers, none of which handle course work.
I don't know what to do... To submit my UCAS application I need to state the center at which I'll be finishing this course...

Are there tutors that could mark my work etc, then I could sit the exam at a center?

I've scraped 10 pages of google for centers, I've literally had about 30 replies so far in the form of "Unfortunately, you wouldn't be able to complete the course at this center, as we do not handle course work."

I have 10 DAYS to sort this out, or I'm not going to university this year.
