I want the assignments in my class to be private. This means I need to upgrade my organization plan, right? Since I pay per month, per user, it's getting pricey. Am I missing something?
GitHub provides a no-cost solution for teachers. In one of the GitHub Classroom videos it mentions that if you require unlimited free, private repositories you will need to apply for an academic discount for your classroom organization at https://education.github.com.
Please upload proof of academic employment (such as a faculty ID or employment verification letter from the school) with your application.
Hope that helps!
