Mock tests
85 real exam questions. One per screen — answer with a click or theA–D keys, verdict lands immediately, Why opens the rule behind it. Nothing is recorded — each question stands on its own and a reload starts clean.
The answer keys are community-sourced and thin. 76 of 85 have nobody's vote behind them — one anonymous submission each. Of the 9 that were checked, the community votes against the listed key on 5. Every verdict carries a chip saying which case it is, and the chapters win any disagreement.
- 85Full set
Every question in the order the dump has them, scenarios interleaved — closest thing to sitting the paper.
- 16Multi-agent research
You are building a multi-agent research system using the Claude Agent SDK. A coordinator agent delegates to specialized subagents: one searches the web, one analyzes documents, one synthesizes findings, and one generates reports. The system researches topics and produces comprehensive, cited reports.
- 16Customer support
You are building a customer support resolution agent using the Claude Agent SDK. The agent handles high-ambiguity requests like returns, billing disputes, and account issues. It has access to your backend systems through custom Model Context Protocol (MCP) tools (get_customer, lookup_order, process_refund, escalate_to_human). Your target is 80%+ first-contact resolution while knowing when to escalate.
- 15Claude Code workflow
You are using Claude Code to accelerate software development. Your team uses it for code generation, refactoring, debugging, and documentation. You need to integrate it into your development workflow with custom slash commands, CLAUDE.md configurations, and understand when to use plan mode vs direct execution.
- 15Developer tooling
You are building developer productivity tools using the Claude Agent SDK. The agent helps engineers explore unfamiliar codebases, understand legacy systems, generate boilerplate code, and automate repetitive tasks. It uses the built-in tools (Read, Write, Bash, Grep, Glob) and integrates with Model Context Protocol (MCP) servers.
- 23No scenario
Questions the dump stripped the scenario from. They stand alone: tool design, error handling, escalation policy.
1 of 85 questions have a written explanation. The rest say so and send you to the chapters — a rule gets written after it is missed, not before.
