B-5: Basic Cornering Theory
This test is extremely hard!
Brake a lot later into the corner than the driving guide tells you to and brake hard. The key is to brake properly while picking the right line through the corner - if you apex too soon you'll run wide on exit and into the dirt or have to lift.
The apex of the corner (in layman's terms) is the ideal point of the corner where you want your inside tires the closest to the curb. You can also think of it as the point where the entrance of the corner transitions to the exit.
Once you get on the power after the apex you want to keep it on the floor until you cross the line.
Even with all the examples in the world, it'll probably take you much longer to complete this test than any of the other B tests.
Note * Played with a regular six-axis PS3 controller.
