For level 2 which is all you would need for most events is fill out the form and pay money ( noy sure but will check , I think under $100 )
For level 3 or National Rally fill out a form , pay more money , do an online test ( bout $200 )
For level 5 or International Rally , fill out form , do medical , pay LOTS more money ( bout $600 ) and do an online test.
For racing , totally different and XRW is pretty up on it cos he was the AFARCC CAMS steward last year.
