The flight simulator for
professional dev fundamentals
Scenario-based code review practice, security training, and git workflows. Build the skills every engineering team assumes you have on day one. Scored on reasoning, not just answers.
3 scenarios per category free. No credit card required.
Scenario
Fintech app. SSNs and credit scores in the database. Find every PII leak before it ships.
Your analysis
Click lines to flag suspicious code. Explain your reasoning. Get scored by AI.
After submitting, you get a full debrief: what you found, what you missed, and why each issue matters.
8 hands-on scenarios. Review Copilot output, MCP server configs, AI agent tool calls, and more. GitHub teaches you to use AI. We teach you to review what it produces.
CS programs teach computer science.
Nobody teaches how to function on a real team.
Git workflows, testing strategy, PII protection, observability, debugging under pressure. These are table stakes at your first software engineering job. And they are almost universally untaught.
How it works
You're dropped into a realistic scenario - a PR review, a failing pipeline, a suspicious log. Context and pressure, like a real team.
Flag suspicious code, trace the root cause, write your reasoning. We score how you think, not just what you find.
Full breakdown of what you caught, what you missed, and why it matters in production. Then a variant to build pattern recognition.

AI writes the code. You own the outcome.
Copilot can generate a feature. It cannot take responsibility for a production outage. Directors of Engineering are already shifting what they hire for: the ability to audit, explain, and own.
Practice reviewing AI-generated code before it ships to production. LearningTo.co trains for the interview that actually exists now.
