While it is generally considered good policy to use any cryptographic software 
on a computer you do not trust, given your reason for wanting to use GnuPG on 
the untrusted university computer, I have a suggestion.

Make a Live GnuPG USB thumb drive - make sure that you set the default path to 
be the USB drive, and not the HDD of the university computer.  Thus all of your 
keys would be on the USB drive and none on the untrusted computer.  If your 
private keys are already on the untrusted computer, then I can only suggest 
revoking them and creating new ones on a trusted computer - with the keyrings 
stored on the Live GnuPG USB drive.
