An OA tomorrow? An interview in an hour? Last Min Prep is Launchpad’s revision series for exactly those moments. Instead of re-reading everything, you get short, ready-made sessions that help you revise what matters, recall it faster, and walk in clearer.

How it works

One Question to Start

Click Start a quick revision and begin right away — no setup needed.

Ready-Made Sessions

Each session groups a few related topics and takes about 10–20 minutes.

Learn by Doing

Recall prompts and explained checks help you remember, not just re-read.

Pick what you are preparing for

Sessions are grouped by track, so you can revise only what your next round needs:
  • DSA & CP — arrays, search patterns, trees and graphs, DP, greedy, and more
  • Full Stack — JavaScript, React, CSS, APIs, auth, and SQL
  • Core CS — operating systems, memory, concurrency, databases, and networks
  • Aptitude — percentages, ratios, reasoning, and problem solving
  • Interview — technical interview concepts
  • AI & Data and Programming
Each session card shows how long it takes, how many topics it covers, and how much you have completed.

Know what you are revising — and why

Every concept card tells you:
  • What role it plays — for example a core pattern, a pattern builder, or proof practice
  • Where it usually shows up — for example coding OAs or contests
  • What to remember — one key point to keep in mind
  • Revise topic and Revision tools — to dive deeper when you have more time
