Motorcycle restricted test

What is the difference between the regular restricted test (which you have to wait 6 months after completing leaners to attend), which is called the "Practical test option," and the CBTA test (which you don't have to wait 6 months after completing learners to attend), called "CBTA option"

I've seen the cbta test being conducted, is it similar to the practical test option? Do they just allow more faults?

What sort of things are tested differently?
