F1 2013

This can be done on any difficulty (My suggestion for Easy for beginners which will earn you bronze medal) and on any scenario (Classic included which can be found on Classic Mode).

Now, I won this on Classic scenario, but the easiest one is The Rookie Challenge which can be found on Proving Grounds. It was the Melbourne challenge as Marussia where you start 21st and try to get ahead of your teammate (Jules Bianchi, whom is 17th) on 3 laps.

You can easily overtake the cars in front, Including Bianchi on either the straight, to turn 1 and turn 2 in 1 lap, otherwise if you are struggling, I have put a video on here to guide you visually.
