Practice that teaches, not just tests
ArchPrep is a free, independent study tool for engineers preparing to build production AI systems with Claude. It exists for one reason: realistic practice with explanations beats memorizing dumps.
What's inside
6 timed mock tests covering 50 questions across the core competencies: Claude API fundamentals, prompt engineering, tool use, agents and MCP, retrieval-augmented generation, and safety and responsible deployment. Each test scores against a 70% practice bar and explains every answer.
How the questions are written
Questions are original practice material written to resemble certification-style problems. They favor durable concepts (how the Messages API is shaped, why chunking matters, when to reach for an agent) over volatile trivia, so the bank stays accurate as products evolve. Nothing here reproduces any official exam.
