How to Build a Consistent DSA Revision System
Interview prep usually breaks because revision is random.
Why revision matters
Solving once is not enough. You need a system that helps you revisit problems before you forget them.
A simple revision loop
- Solve a problem.
- Write a short note about the key trick.
- Revisit it after a few days.
- Mark whether it felt easy, good, hard, or forgotten.
What to track
- short note
- last approach
- weak topics
- revision confidence
Final advice
Do fewer problems, but review them properly. Consistency beats volume in the long run.
