Defensive Driving Test Drivers

defensive driving test drivers
Help would be a defensive driving course to prepare for a test Drivers Ed?

I have to do a test and 30 hours of this, more of a 6:00 defensive drving a ticket for driving without a license (in 15), so I have to do Drivers Ed, but I know if I have to study things Drivers Ed or conduct defense will be to prepare?

Honestly, to have a chance?
