It could depend on the State you're taking the test in.
The written part I say is the hardest. But the driving part is usually a breeze. If you've been practicing driving and are confident in yourself then you should be able to pass the drivers test without problems.
I know for me 12 years ago I took my Drivers test for my permit in Mena Arkansas at the age of 16.
I passed the written test and when I got in my truck to take the drivers test I was surprised that the tester only asked me to drive around the post office and then stop at the stop sign and then head back over to the dmv that was just across the street.
Before we got back to the dmv she had already signed my papers and passed me.
But I'm sure yours will be a bit harder. But it's not that hard.
Good luck with your test. I hope you pass.
