Scholarship links are dead and here is another way to get Edu backlinks.
1. Search for US universities that have a "Directory" page on them. Usually this directory is the list of alumni, present students, and teachers.
2. Filter out current students and scrape their emails.
3. Almost all university students have access to university blogs and you just have to tell these students that you'll pay some $$ for posting an article. And make sure you write something useful for the people and no BS.
Works like a charm! Give it a try
Wanna know what's even better?
Scrape Ahrefs for Edu sites with broken links OUT sites, then sees if they are available to register. I have about 5 domains of students that had to register it as a project and abandoned it after graduating. The domains all have a direct link from the university lol.
Any site I link to from these domains is a grandchild of an edu link.
