What happens if you can’t pass or do you make sure everyone gets passed also how many people have you seen not pass

study hard, then go take your test, if you fail the first time around at least then you know exactly what you need to work on, best-case scenario you'll pass your first time on everything.

You literally cannot fail if you study.. Repetition, repetition, repetition, ect... their instructors know what to look for and will tell you what/where/how to study/practice.

They will keep giving you opportunity to pass as long as you follow their advice and study structure.
