How TieEdu courses work
Every TieEdu course is a fixed sequence of modules and lessons. Nothing is unlocked out of order, so a lesson you have reached is a lesson whose prerequisites you have already met. Progress is recorded on the server as you read or watch, which is why it survives a cleared browser and a new phone.
Ratings on this page come from learners who finished the course and submitted feedback — an unrated course shows no rating at all rather than a made-up one. Learner counts are enrolment records, not impressions. The same rule governs completion and XP: the server credits time at real-time speed and caps how fast a lesson can be marked done.
4 of these courses are free to start. Finishing any of them issues a certificate signed by TieEdu, and its serial can be checked by anyone at tieedu.com/verify without an account.
Use the filters to narrow the list by beginner, advanced level and by topic — currently free, placement, tools, algorithms, architecture, autocad, backend, bash, among others.
