Anthropic put out the Claude Certified Architect — Foundations (CCA-F) exam, and the official study material is a Skilljar course plus scattered docs. There were a few community study repos floating around, mostly raw markdown lists of questions. I wanted something I could actually drill on between meetings, on my phone, without signing up for anything — so I built one.

Live at ericspencer.us/Claude-architect-quiz. It’s 115 flashcards across 7 weighted domains: agentic architecture, tool design and MCP, Claude Code workflows, prompt engineering, context management, cross-cutting topics, and a Q&A bank that mirrors avidevelops/claude-architect-exam-prep so the well-known practice questions are in there too. The domain weights match the exam guide, so if you cram you’re cramming on roughly the right stuff.

There are three modes. Cards is the standard flip-and-mark-known loop. Quiz is multiple choice with explanations and a per-domain score breakdown at the end, so you can see which area you should go back and read on the Anthropic docs site. Cram auto-cycles and weights toward the cards you marked for review, which is the one I actually use the most.

The whole thing is a static site — plain HTML, CSS, and JavaScript, no build step, no framework. data/flashcards.json is the single source of truth. Each card is just:

{
  "id": "unique-slug",
  "type": "multiple-choice",
  "question": "...",
  "options": ["A", "B", "C", "D"],
  "answer": "text of correct option",
  "explanation": "Why this is correct + common gotchas",
  "difficulty": "medium",
  "tags": ["..."]
}

Progress lives in localStorage. Nothing gets sent anywhere — there’s no backend to send it to. If you clear your browser data, your “known” pile resets. That felt like the right tradeoff for a thing you use for two weeks before an exam and then never again.

The one design choice I cared about was making it keyboard-first. If I’m grinding through 115 cards I do not want to be moving my mouse between every card. C jumps to cards, Q to quiz, R to cram, S to stats. Space reveals the answer, J marks for review, K marks as known, 1–9 picks a multiple-choice option, ? opens the help overlay. You can run a full study session without touching the trackpad, which is what I wanted from the other study sites and never found.

Content was compiled from publicly available sources — the two community repos linked in the README, the Anthropic Academy program overview, the actual platform docs for prompt caching / tool use / batches / MCP, and a few longer write-ups on Dev.to and Medium. Not affiliated with Anthropic in any way, and I make a point of saying so on the site. Always cross-check against the official exam guide before you take the thing.

If you spot a wrong answer or a domain that’s underweighted, the source is right there — open a PR on the repo or just file an issue. I’ll keep updating the cards as Anthropic updates the exam.
