The method

The course method adapts socratic-tutor by Jane Street, released under the MIT License. We adapted it from a live chat tutor to a self-serve web course. The course content is mrkts' own. Jane Street does not endorse mrkts. See socratic-tutor on GitHub.

  • The topic is split into ten subskills, one module each, with a skill map from 0 (unaware) to 5 (can teach it).
  • An optional placement quiz lets people who know some of this skip ahead. It never places anyone above 3.
  • One question per screen. Each module teaches first, a section at a time, with a question after each idea. A wrong answer gets a narrower question; two misses on the same idea bring that section back.
  • Level 4 takes two right checks on different questions, one of them recalled unprompted: in a later session or after another module, never right after the lesson or a revealed answer.
  • Level 5 takes the module's edge case and teach-back (spot the flaw in a beginner's explanation).
  • Right answers come back for review after 1, 3, 7 and 14 days, mixed into later modules without warning. A missed review costs a level.
  • The final mixes every subskill and ends with one integrative scenario.

All prices in the course are illustrative example numbers, not real quotes. Some come from a Black-Scholes calculation with no rates or dividends, rounded. The implied move (ATM straddle ÷ stock price) is a rule of thumb. Sizing percentages are example policies, not recommendations.
