OK, I can see that structure and how it would work for my situation, for example I am doing a course for an "optometriic technician" so the 4 levels would be:
iTech Crash Course > Pretest > Visual Acuity > Snellan
I have both written material in PDF and in video in MP4 for this course. I have exam questions to ask to certify the learner has absorbed the material.
Where do I load this material, on what server and where?
For the questions, what are markdown documents and / or exercise formats?
