Everyone has AI. Learn to drive it.

The Prompt Lab is where you master prompt engineering for real. Write a prompt, watch live AI turn it into code, then we run it on hidden tests and score it. Vague prompts fail; precise ones win — that's the skill.

• Code, Concept & Trend challenges — 30 and counting
• Specificity scoring + coaching on every prompt
• Live AI grading · leaderboard · A/B compare

Learn it. Then sit it.

Pick your board — Cambridge IGCSE, AS & A Level (9618) or IB. Every syllabus topic is mapped to a CodeArc tutorial, so you learn exactly what's examined. Then sit an AI-marked past paper that tells you precisely which topics to revise.

• Full syllabus mapped, topic by topic
• AI marks your paper like an examiner
• Areas of improvement + “revise these” links

Everything you need to go from curious to capable

Not another video course. CodeArc is built around doing — and it grows with you, from your first line of code to teaching a whole classroom.

• In-browser playground — Write and run real code in 12+ languages — sandboxed, instant, nothing to install.
• AI tutor that teaches — Inline suggestions and fixes that nudge you toward the answer instead of handing it over.
• Structured tutorials — Card-based lessons mapped to the school curriculum, with an editor in every step.
• Coding challenges — Auto-graded problems across difficulty tiers. Track your score, revisit weak spots.
• Learning games — Game Lab turns the fundamentals into something you actually want to keep playing.
• Progress & XP — Levels, streaks and badges that show exactly how far you’ve come — and what’s next.
• Exam Mode — board-aligned — Timed, AI-off practice papers styled on Cambridge IGCSE & A-Level, AQA, OCR and IB — with mark schemes revealed after you submit.
• Built for classrooms — Teachers set AI-generated auto-graded tests, mark written work against the scheme, and track competency by syllabus strand.
• Made for families — Parents follow each child’s progress with a clear, friendly weekly report.
