If you've got a wheel and want a real challenge, try getting golds with traction control off, ABS off, and skid recovery off, and use the clutch pedal. It makes a huge difference in the level of difficulty. I generally turn all of these driver aids off since real race cars don't have them. Managed to get gold in all the A and B license tests so far using these settings (except for the Top Gear test with the Lotus Elise, I could only get bronze with these settings - it is physically impossible to get Gold on this test without turning TC, ABS, and Skid Recovery on since the Lotus is so snappy loose and you have to drive like crazy to pass 11 cars in two laps.).
