| Rank | Source | Why this rank | Time |
|---|---|---|---|
| 1 | Official Anthropic Exam Guide (PDF) | Source of truth. Every subdomain, every Knowledge/Skill bullet, the 6 scenarios, the weighting. CertSafari and Paul's guide both derive from this. | 2 hr |
| 2 | Paul Larionov's GitHub guide (guide_en.MD) | 116 KB of dense theory chapters + per-domain notes + 12 worked example questions + 20-question practice test. Closest thing to a free official study manual. | 4-6 hr |
| 3 | CertSafari | 615 free practice questions with explanations. Reproduces the official skills-measured guide verbatim. Domain Mode for targeted weak-spot drill. | 4-8 hr |
| 4 | Anthropic Cookbook (GitHub) | Real code patterns. Most useful for the Tool Design / MCP / Agent SDK question types where seeing actual JSON schema + tool_use code locks in the concept. | 2-3 hr |
| 5 | CyberSkill mock exam | 60Q / 120-min proctor-style timer. Maintainer is a CCAF Early-Adopter pass-holder. Tests exam flow + endurance. | 2 hr |
| 6 | Claude Cert Guide (claudecertificationguide.com) | 30 lessons + 4-scenario mock. Format differs from official (their mock is 25Q/60min, not 60Q/120min) but lesson structure is clean. | 3-4 hr |
| 7 | Anthropic Skilljar courses (Claude 101, Building with Claude API, Intro to MCP, Claude Code in Action) | Use only if a specific concept isn't clicking. Don't try to watch all four — they cover too much off-exam material. | variable |
