Roadmaps, Libraries, and a Larger Problem Bank

A practice platform only works if the next problem is worth doing. This phase focused on making the library larger, easier to navigate, and more useful across the product.

What changed

We invested in the problem bank, catalog search, and roadmap-style organization. The goal was not just more questions. It was better surfaces for choosing the right question: by topic, difficulty, format, and learning objective.

That matters across the whole platform. Compete needs fair, fast rounds. Classroom needs problems that fit a lesson. Assessments need questions that can support evidence, variation, and review. A larger library is only valuable if it is structured enough to serve all three.

Why it matters

Students can grind random problems forever and still miss the pattern they needed to learn. Educators can spend hours searching for a good example. Recruiters can accidentally measure the wrong thing because the question was convenient rather than diagnostic.

Roadmaps are the antidote to that randomness. They make practice feel intentional. A learner can see the path from arrays to graphs to dynamic programming. A teacher can pull from the same source without rebuilding the curriculum from scratch.

Where it points

The larger library is the base layer for [Compete](/product/compete), [Classroom](/product/classroom), and [Assessments](/product/assessments). Over time, the same catalog should power practice, live teaching, and benchmark-backed evaluation without each lane inventing its own content world.
