Everything you need to know
Which one for which goal
For school subjects and basics, Khan Academy is hard to beat. For university-level content, Coursera and edX are strong options. For short practical skills, Udemy has a large catalogue.
You do not need to choose only one: many learners use two platforms at the same time.
Keeping motivated
Online courses are easy to start and easy to abandon. Set a small weekly goal, like finishing one module, and track your progress.
Studying with a friend or sharing your progress can also help you keep going.
Learning with little data
If your mobile data is limited, download lessons on Wi-Fi and study offline. Khan Academy, Coursera and edX offer download options in their apps.
Lowering the video quality also helps save data.
Building a learning plan
Choose one main platform and one course at a time. When you finish, pick the next course that builds on what you learned.
A simple plan with small goals keeps you moving forward.
Quick summary
Khan Academy for fully free basics, Coursera and edX for university courses you can audit, and Udemy for practical skills. Try one and keep what fits your routine.
The best app is the one you actually use every week.
