M1.3: The Clock-Face Remainder Bucket
Bottleneck: The brute-force bottleneck this module eliminates — see M1.3-modulo-cycling-remainders/README.md.
Pre-launch
This module is still in the pre-launch phase.
This site is a YC preview. Only M0.1 — memory boxes and the 10^8 ops/sec clock — ships video, audio, the quiz, and the toy. M1.3 stays on the syllabus so the map is honest; the filmed lesson is not in this build.
