What enrolling gets you
The same things whichever course you pick.
- Lessons in order, not a playlist
- Each course runs as a numbered sequence, so you always know which lesson comes next.
- Sheets that track what you solved
- Practise on the DSA sheets by topic. Every problem you finish moves your tracker.
- You land back where you stopped
- Every lesson you finish is saved, and the link reopens on the one you have not seen.
- Nothing to pay and nothing to cancel
- Enrolling takes one tap and costs nothing. There is no subscription waiting behind it.
- Progress you can see
- Course progress and solved problems both show up in one place, not in two tabs.
- A next step when you are ready
- Free courses cover the foundations. Paid tracks add projects, mentorship and career work.

Free courses cover the foundations. Paid tracks add projects, mentorship and career preparation.
