Alpha Tracks
Structured paths, sequenced by dependency
A track is a guided sequence: learn a technique, practice it immediately, then advance. No more wondering what to do next.
.NET Foundations
BeginnerLearn C# the way the judge wants it: the Solve contract, parsing, strings, arrays and dictionaries — then apply them to real problems in the lab.
2 weeks · 3 modules
You'll be able to
- Write judge-ready C# from memory
- Solve two-sum, anagram and stack problems
- Read Big-O out of idiomatic .NET code
Modules
- 01C# Essentials5 lessons · 4h
- 02Hashing & Classic Problems5 lessons · 6h
- 03Think in Complexity5 lessons · 3h
Programming Foundations
BeginnerThe ramp-up track. Big-O thinking, warm-up warm-ups, and the intuition that makes everything else click.
3 weeks · 4 modules
