The problem
Most ICGB prep is a dense PDF you stop opening by week two.
KataPrep breaks the body of knowledge into small daily reps you can feel yourself clearing — so studying becomes a streak you don't want to break, not a chore you keep postponing.
How it works
Three stations. One daily habit.
02
Daily kata with Master Daru
Short, spaced practice sets, resurfaced right before you'd forget them. Daru keeps your streak alive and pulls you back tomorrow — the part of studying that's hardest to do alone.

Know when you're ready
A readiness score tracks how prepared you are across the whole blueprint, so you book the exam when the data says you're ready — and walk in calm instead of guessing.
