The only way you may continue is to convert the trial to a paid version... that 30 days is an absolute limit... no extensions
If you can't afford Premiere Pro... go to the products section (click the big red A at the top left) and look at Premiere Elements
I would pay for the full version but the problem is that within a few months I will be recieving the entire Master Suite from the college I will be attending.
But if I were able to download the Premiere elements, would I be able to open the project file from CS6?
Perhaps you might have a classmate with a different computer
who is interested in trying the 30 day trial for themselves?
If so, you could let them test drive the software using your
Project file and media (and export your cut for you).

Be sure to read "Note: Very Important Instructions".
The only way to solve this is to buy the product.
Or find someone who owns it and will finish it for you.
