Hello

I'm searching for an alternartive to Shika. My customer website functions like that : Students send him offline payment . Then they get id and password to access hidden courses (only "level 1") : 17 modules separated in lessons. For each module they have a quizz , which success unlocks next module access. All courses are "free" (because prepaid offline). Is that possible with SP LMS. I put all courses as free but dont have any button to "enroll" ! Thanks for all. https://prnt.sc/8qd4PZ6PNF5F
