# 🧗 CP Ladder
> Climb Launchpad's CP Ladder with rating-banded problems, Guided Mode, topic filters, notes, timer, a global heat map, and leaderboards.
The Launchpad CP Ladder is your structured path into competitive programming. This page covers how the ladder is banded by rating, how Guided Mode helps you progress, and the tools you get around each problem, including notes, a timer, a global heat map, and leaderboards.
Follow a recommended order through the ladder so you always know what to solve next.
Focus on a specific topic like graphs, DP, or greedy when you want targeted practice.
Visualize your consistency at a glance across every day you have practiced.
Compete on weekly and all-time leaderboards to see where you stand.
## Open from day one
The CP Ladder is open from your very first visit to Launchpad. There is no lock, no gate, and no prerequisite course to finish first. If you want to start with competitive programming today, you can.
## Rating bands
Problems on the ladder are organized into rating bands so difficulty ramps up smoothly. Pick a band that matches where you are today and climb from there.
## Guided Mode
Guided Mode picks the next problem for you inside your current band, taking the guesswork out of what to attempt. Use it when you want a study session that just flows.
## Topic filters
When you want to shore up a specific weakness, filter the ladder by topic. This turns the ladder into a focused topic drill without leaving the environment you already know.
## Notes and timer
Every problem supports notes so you can save the observation, template, or trick that made it click. A built-in timer lets you time-box attempts, which is closer to how contests actually feel.
## Global Heat Map
The Global Heat Map turns your practice into a calendar of colored squares. It is one of the most satisfying ways to see momentum build over weeks and months.
## Weekly and all-time leaderboards
Two leaderboards keep the CP Ladder competitive:
* **Weekly leaderboard** resets each week, so it rewards recent effort.
* **All-time leaderboard** captures your cumulative climb across the entire ladder.
Progress on the CP Ladder stays with your account. Your solved problems, notes, and heat map are retained as your access continues.
