FROM THE ALEKSANDRA EDTECH WORKSHOP
School Timetable.
Everything fits.
Almost.
Five days. Dozens of lessons. And one teacher who still has not mastered being in two places at once.
One real school scheduling puzzle.
And my response: “Wait. Perhaps I could build something for this.”

to fit in…”

HOW I ENDED UP BUILDING ANOTHER TOOL
I had not planned
to build a timetable.
I was not responsible for the school timetable. Nobody asked me to build a program. I simply wondered whether all the combinations — teachers, classes, rooms and endless “but what if” constraints — could be turned into a tool.
And of course, I had to try.
What began as a self-imposed challenge became a tool for arranging, checking and exploring possible schedules.
The tool was not adopted for daily use at the school. It remained an experiment — and a chance to explore how a genuine organizational challenge could be broken down into rules, constraints and possible solutions.
Here you can explore its public demonstration using fictional data.
I wanted to know whether I could. Along the way, I learned far more than a timetable could ever show.
A SMALL TEST OF A BIG PUZZLE
Everything is in the right place.
Except the teacher.
One teacher, two classes, same time slot. Move one lesson and see what happens.

For now, the teacher would need to clone themselves.
WHAT CAME OUT OF IT
A little less chaos.
A clearer overview.
From data and rules to alternative timetables — with room to inspect, rearrange and save them.
Find the “but what if”.
Constraints, availability, workloads and potential clashes — in one place.
Change perspective.
Views organised by class, teacher and school resources.
What if I swap these two?
Make manual changes, swap lessons and explore alternative solutions.
No need to start over.

ENOUGH TALK. OPEN THE DRAWER.
Here it is.
The actual program.
Explore the public demo with fictional data. A separate tab gives you more room, especially on a smaller screen.
