How to book your test
You can book in person at the RMS (or Service NSW) office; you can phone them; you can book online - your choice! If you book a test but then feel you're not ready you can defer it at no cost, so long as you don't do it at the last minute. Discuss the booking with your driving instructor, especially if you want to use his or her car!
How is the test conducted?
Your test will take about half an hour. It will include either a reverse park or a three point turn, but you won't know until the day which one it is. It will also include a kerbside stop. The best thing you can do beforehand is to read the Guide to the Driving Test, which would have been given to you when you got your Learner's Licence.
What car should I use?
I recommend using the car you are most comfortable driving. Sometimes this will be the driving school car, sometimes your own. It must be clean and roadworthy. The examiner will inspect it before the test, so be sure that all lights work properly and that tyres have legal tread. The RMS or Service NSW centre does NOT supply cars for tests.

Is a pre-test lesson a good idea?
You bet it is. Nerves play a big part in this and your driving instructor will help to alleviate some of this stress by doing a drive beforehand. Many a student has failed the "pre-test" yet passed the real one with flying colours!
Indicating off Roundabouts
I'm asked about this all the time as it's a relatively recent rule.

The road rule states that a driver must indicate LEFT to exit a roundabout "where practicable". Hmm, who defines practicable? I take the view that if a student indicates to exit EVERY roundabout, they can't possibly be marked down, so let's go with that. So how is this done? The following assumes a typical 4-way roundabout.

If turning left, enter the roundabout with your left blinker on and leave it on until you have completed the turn.

If going straight ahead, there should be NO indicator on entry. Indicate left as you pass the first exit. This means "I am taking the next exit".

If going right, indicate right on entry, pass the first exit with your right indicator still on. As you pass the second exit, change from right-blink to left-blink.

You may well be curious about those roundabouts with funny angles, where "straight ahead" is actually slightly right (for instance). Here's a tip: follow the arrows on the road. If the arrow points straight ahead or at a slight angle, then don't indicate. If the arrow points left or right, then use a blinker to indicate that.
