Gradings are special classes where students come to be assessed on their progress and are then awarded the relevant colour belt.
Before attempting their next grade, students must complete a certain number of classes and show ability to perform relevant karate techniques from the syllabus.
At that point, their Sensei will confirm the grading date and send out an email with the details.
At each grading, there are a few places available for people who wish to come and train.
Why would someone want to do an extra hard class? - Accelerate their progress - Sharpen up all their techniques - Test their fitness level - Prepare for their actual grading
