F1 2011

Go to Challenge mode in the Main Menu. There are 10 "levels" in challenge mode. In each level there are initially five separate challenges. You can receive a grade from an "E" to "A 3 stars" on each challenge. As soon as you complete three challenges receiving a "C" or higher, you will unlock a final challenge. Complete this challenge with a "C" grade or higher to advance to the next level. Again, there is no need to complete every challenge. Complete the minimum to advance through each level to reach Level 10 in the fastest amount of time. By completing the final challenge on Level 10, you will unlock Champion and will have unlocked all of the other challenge related trophies along the way - as long as you have at least received one "A" grade. The challenge mode is pretty straightforward and moderately easy. I would suggest always completing the cornering, overtaking, and checkpoint race challenges as they seemed easier than some of the other types.
