Ah, the wet circle test. Are you having trouble passing it or getting gold on it? It is not that different from the dry circle, only that you can spin out more easily. You should watch the demo and keep an eye on the speedometer and note the speed range. Once you know how fast you should be travelling, you should work on the acceleration. Getting a good acceleration can save you as much as a tenth of a second. Try to maintain contact with the rumble strip, not because it gives you better grip, but you'd have a smaller radius, which means less distance to travel, which means better time. Note the lap times of the demo and try to keep up. Some people like using ghosts, I personally don't. Be careful that the rumble strip doesn't bump you into the cones. A common misconception about this test is that you should be steering right the entire time, that is simply not the case. You will be tapping right a lot, the idea here is to maintain speed and control. You are not trying to go faster here. You are trying to travel in a smaller circle. If you try to go faster, you'll find that things will start to fall apart rather quickly. Good luck.
