That said, you might still want to contact Apple in case they can accommodate your needs.
I'm a student with a personal Apple ID. Can I get the full version for free as an individual?
Unfortunately, this is not possible, since Goodnotes is currently offered for free through Apple School Manager only. Please contact someone in charge of purchasing digital content at your institution so that they can get the full version for you as an institution.
Where can I find more information about Apple School Manager?
Please browse further resources on Apple Education Support and contact the Apple team with any questions you might have.
