How the forecast works
Forecasts, not leaks. Probabilities, not promises.
01
Ingest
Ten years of past papers, mark schemes, and every syllabus revision go into the model.
02
Model
Topic cycles, mark weightings, and setter patterns become a probability for every topic in your syllabus.
03
Publish
You get the forecast. After the sitting, we publish what hit and what missed — in public, every year.
A forecast can be wrong — that's why the accuracy scorecard is public and the guarantee is real.
