YO, i also had trouble winning S liscence(you mean gold right)... BUT my easiest was the GT one at MONACO and the PENZOIL at MIDFILED... my most recent golds are the MAZDA MIATA at TRIAL and the VIPER at LAGUNA,,, i just finished those about two weeks ago... HERES THE MOST VALUABLE INFORMATION YET.... put down the game!!!!!!! or at least stop trying for a while.... maybe a week who knows... you have to realize that today is not going to be the day, and move one. JUST COME BACK TO IT... but what these guys said about racing the car around the track is very much true...
oh YEAH AND WATCH THE DEMO AFTER YOU DO A VERY FAST LAP.... becasue the demo will play and your replay will play as your ghost, by doing this you can see where you messed up at and where you were doing good at.
PEACE
