Why there's no fee
Money shouldn't decide who learns to code
Theme Seva means "service" — that's the whole model. We cover the cost of teaching so a student's background never decides whether they get to learn.
- No tuition, ever — not even a "registration fee"
- Taught by working developers and designers
- Every course ends in a project for your portfolio
- A free certificate when you finish
