If you study really hard and remember the questions and answers then the test is pretty easy to pass.
That's one thing you should do is study the drivers permit handbook more than once and do it again the day or night before your drivers permit test so the questions and answers will be fresh in your mind.
Then if you pass the written test you will go onto the driving test where you actually get into a car and drive with a tester who will score you on your driving skills and your ability to operate the vehicle including the controls in the vehicle.
Don't mess with the radio though when you go for the driving test as they will likely fail you.
