Which study option suits you when learning to drive in QLD?
If you like reading, use the handbook and qld.gov.au. TMR calls Your keys to driving in Queensland the road rules handbook for all drivers, learners included.
If you want structure, PrepL takes about 4 to 6 hours, with activities, videos and scenarios, and you have 12 months to finish. It costs $29.70, the same as the written test, and ends in its own 30-question test.
Private apps are handy for drilling questions on your phone near the end. None of them are TMR's, so check anything that surprises you against the handbook.
For the driving itself, TMR's advice on driving schools is to ask to see the trainer's Industry Authority card, which shows they're accredited, and to check the car has dual controls, which the law requires. It suggests lessons of 1 to 2 hours.
