OPEN FORMATS · ORIGINAL PRACTICE

Study with your tools.

Give Claude, Codex or another assistant a specific question and a checked reference—not an instruction to improvise a whole curriculum.

A useful starting prompt

Use Accretive Thinking’s original IB question bank. Ask one question at a time.
Let me state assumptions and explain my reasoning before showing the solution.
Check numerical answers with the local checker. Probe conceptual mistakes separately.
Give feedback tied to what I actually said, then ask the retry with new numbers.
Do not invent interview questions from specific banks or assign offer odds.

Local tools for Claude Code or Codex

node study-cli.mjs list
node study-cli.mjs question dcf-ufcf
printf '%s' '{"ufcf":47.5}' | node study-cli.mjs check dcf-ufcf first

The question command omits the direct answer fields. The checker reads answers from stdin and returns expected values, matches and feedback. It runs locally without a model or API key.

Local HTTP checker

Run node server.mjs. The loopback-only endpoint POST /api/check accepts a question ID, first/retry attempt and numeric answer object. See the practice-loop reference for the exact Origin header and request schema.

Know the limits

A numerical match is not semantic grading. Use the conceptual probes and review written explanations separately. The bank is original and formula-tested; expert pedagogical review is pending. Voice requires a separately configured API key and consent. No model subscription or hosted MCP server is bundled here.
