You can't have security on a machine which is out of your control. If
others have physical access to your machine at university, what you
want isn't possible. They could simply install a keylogger or other
monitoring.

(Btw: here in Norway, the results of your exams are never sen2d via
email. They get send to you via a specially designed "website"
(StudentWeb) which you can connect to providing your identity number
and using encryption. Here's an example, choose one:
