The ProblemAnthropic’s Claude Certified Architect exams (CCAR-F &amp; CCAR-P) test real scenario judgment, not documentation recall. Official resources give only sample questions, so most engineers have no clear signal of readiness.Existing practice sites have three common problems:<ol><li>Aggressive gating — email, account, or credit card before you see a single scenario</li><li>Coarse feedback — domain-level scores without telling you which exact skill is weak</li><li>Documentation drift — exam blueprints freeze while SDKs, MCP, and APIs keep changing</li></ol>What I BuiltClaudeArena is a free, privacy-first practice engine for AI engineers and solutions architects preparing for the CCAR exams.• 950+ original scenario questions focused on agentic workflows, subagent isolation, and tool-choice guardrails • Objective-level gap analysis that surfaces precise weaknesses (e.g. “Configure subagent termination conditions”) instead of vague domain scores • Server-side answer validation — no client-side answer leakage • Every question cites the exact Anthropic docs page it rests on • Practice mode needs no account, no email, and sets zero tracking cookiesArchitectural choices• Edge APIs for scoring so the question bank can’t be scraped via DevTools • Heavy real-time audit effort on the Foundations exam (the one getting the next content update) while keeping Professional on the current baseline • Deep page-level citations + automated link health checks to fight doc rotFeedback I’m looking for<ol><li>How do you monitor upstream documentation when URLs restructure?</li><li>Is sub-task / objective drilling more useful in your study flow than full timed mocks?</li></ol>Try a free drill (no signup): <a target="_blank" rel="noopener noreferrer nofollow ugc" class="break-all link-break text-gray-500 hover:underline" href="https://claudearena.dev/app#practice">https://claudearena.dev/app#practice</a>
