Direct-to-student vs institution-mediated access.
Riipen's catalogue is reachable through the courses where your professor has wired it in. If your university adopted Riipen and your specific course is on it, you do challenges; if your school hasn't, or your course isn't, the path is closed unless you join Level UP separately. Ewance is paid by the learner directly. There is no institutional gatekeeper. A student in any country can sign up and start working today.
