课弈Three mobility modes
Switch between fixed-2, fixed-1 and full mobility; class counts are suggested from the combination distribution.

Gaokao elective timetabling (3+1+2)
Keyi suggests class counts from students' 3+1+2 subject combinations, supports fixed-2, fixed-1 and full-mobility modes, builds homeroom and teaching-group timetables, and works out how many rooms mobile classes need.
Common problems
- 12 combinations — how to form homerooms
- Not enough rooms or teachers for mobile classes
- Mobile and homeroom lessons constrain each other

How Keyi helps
Room and staffing estimates
Estimates mobile rooms per period and sections per subject, and compares walk groups by teachers needed at once, to catch bottlenecks early.
Straight into teaching tasks
Sectioning results become homerooms and elective slots, optionally staggered by group, and solve together with all other rules.
Case study
An international school's G9 options: same 19 sections, largest class from 33 down to 26
We re-ran sectioning on the school's real choice sheet (89 students, 4 blocks): every student kept every choice; with the same 19 sections, physics went from 32/18/16 to 22/22/22 and the class-size standard deviation dropped from 6.0 to 2.3, in about 30 seconds.

FAQ
Fixed-2 or full mobility — which should we choose?
Concentrated combinations favour fixed-2; scattered ones favour full mobility. Keyi shows class and room needs for both on your data.
