Launchpad bookmarks and custom lists let you turn scattered practice into an organized revision plan. This page covers how to bookmark any problem, build custom lists for focused study, and use the problem timers and status states that keep your progress visible.

​
Bookmark any problem

Tap the bookmark on any problem you want to come back to, whether it stumped you today or you want to review it before an interview. All your bookmarks land in one place so nothing important gets lost.

​
Build custom lists

Custom lists let you group problems into revision sets that match how you actually study. A few ways students use them on Launchpad:
  • A “Weak spots” list for problems you got stuck on.
  • A “Company shortlist” for problems tied to a specific target company.
  • A “One week to interview” list for last-mile revision.
Build a custom list for each interview you have scheduled. Working the list end to end is a fast, focused way to prep.

​
Timers and statuses

Every problem you practice has a timer and a live status, so you always know where you stand.

​
Problem timer

Use the built-in problem timer as a stopwatch to see how long an attempt actually took, or as a countdown to simulate contest pressure.

​
Status states

Each problem carries one of four states:
  • Not Attempted for problems you have not touched yet.
  • In Progress for problems you have started but not solved.
  • Completed for problems you have finished going through.
  • Solved for problems your submission has passed.
Bookmarks, custom lists, statuses, and timers all live under your account, so your organization system stays intact across sessions.
