At first glance, perhaps this might work:

Since your students are first going through your system and storing a unique
key, your CGI could also generate an HTML download page with that key (or
some other unique identifier) as part of the Web address (ie
http://www.mydomain.com/download/user72635463.html).  And since PayPal
allows you to specify a "thank you" page URL among the cart parameters it
receives, you could include the URL of the download page as the thank you
page.  So when a transaction is completed, the user will be automatically
routed to the download page created by your CGI.

Maybe I'm missing something but this seems like an option.
