Don't follow too closely! I took Young Drivers (Canada) and not once did I remember my instructor ever tell me I was following too closely, and when I took the drivers test the person marked me down a few times for it. They wanted me far, far back to the point where it seemed a bit silly.
Also make sure your car is in good working condition and that you know how to use all of the features. I automatically failed my first drivers test because the parking brake wasn't good enough despite being recently inspected... so I had to get it tightened even further. Nothing more aggravating than that happening! Grr.
