Overview
A daily sheet that will not let you skip mastery.
Kumon shaped how I work: a desk, a pencil, and a worksheet that looks almost too easy until the last problems of the set. You do not skip ahead because you are clever. You finish the sheet correctly, in time, and you come back tomorrow.
Codenda points that method at Python — timed sessions, a streak calendar, and levels that will not let you jump ahead.
The dashboard. Fifteen minutes, then the sheet.
The method
Mastery before advancement
Short drills, one micro-skill per set, scaffolding that fades from fill-in-the-blank to a blank page, and a clock that cares whether you actually own the pattern.
When the set is yours, LeetCode opens — same problem, three tiers: hints, minimal help, from memory.
