The Launchpad DSA Sheet is a curated set of 400 problems organized by patterns, so you build coding intuition instead of memorizing solutions. This page walks through the AI Tutor, notes, streak calendar, and daily study goal that keep your prep consistent from your first pattern to your last.

AI Tutor

Get hints, pattern explanations, and unstuck-me nudges while you solve, without leaving the problem.

Notes

Capture takeaways on each problem so revision before interviews is fast and personal.

Streak Calendar

Every solved problem feeds your streak calendar to reinforce daily practice.

Daily Study Goal

Set a daily target and Launchpad shows an estimated completion date for the full sheet.

​
What you get

  • 400 handpicked problems covering the patterns that actually show up in coding interviews.
  • A pattern-based path that scales from beginner-friendly warmups to advanced problem types.
  • An estimated completion date that updates as you solve, so your prep plan stays realistic.
  • A dedicated leaderboard that ranks students by their DSA Sheet progress.
Pair the DSA Sheet with your study plan so pattern practice lines up with interview timelines.

How to use it well

1

Pick a pattern

Start with the first unsolved pattern block. Patterns are ordered so earlier ones scaffold later ones.
2

Attempt before hints

Try each problem on your own. Reach for the AI Tutor when you are stuck on the pattern, not the syntax.
3

Write a note

Add a short note in your own words about the trick or template. Future you will thank you.
4

Protect the streak

Aim for your daily goal and let the streak calendar do the motivation work.
