Module 1: Study Systems & Habit Formation: Mistake Clinic

This clinic turns wrong moves into reusable judgment. Use it after each practice page and again before the quiz or checkpoint.


Module-Specific Mistake Radar

Start with these traps. Replace or extend them with real mistakes from your own work.

Practice Mistake Checks

Pull any miss from these checks into your mistake log.

Build Your Study System

Source: practice/01-build-your-study-system.md

If your plan still depends on "when I feel ready," then it is not a system yet. If you have no prepared environment and no low-energy version, it is still a wish, not a system.

Diagnostics and Retrieval

Source: practice/02-diagnostics-and-retrieval.md

If you can recognize the concept but cannot generate your own example, the concept is not stable yet. If your metric can be gamed without real learning, the system is pointed at the wrong target.

Seven-Day Habit Reset

Source: practice/03-seven-day-habit-reset.md

Do not track five habits at once. The point is not ambition. The point is visible consistency. Also, do not make the habit so hard that a single busy day destroys the streak.

Review and Adjust Your System

Source: practice/04-review-and-adjust-your-system.md

Do not respond to one bad week by abandoning the system or doubling the difficulty. Review first, then make one small adjustment.


Repair Protocol

For each real mistake:

  1. Reproduce the failure on the smallest example, trace, proof, query, command, or design sketch.
  2. Name the hidden assumption.
  3. Repair the artifact.
  4. Save evidence that changed: failing then passing test, corrected proof step, revised diagram, safer command, benchmark, or review note.
  5. Add one retrieval card beginning with Check... before... or Do not use... when....

Completion Standard

  • At least five real mistakes are logged.
  • At least two mistakes include a counterexample or failing test.
  • At least one mistake connects to an older semester skill.
  • At least one correction changes code, a proof, a diagram, a command transcript, a query, or a design decision.
