Getting silver or gold on all course licenses
Choose "Yes" prompted to use the pace car just before you start your course license test. It helps you get at least a silver trophy, or even gold trophy on the particular test / tracks you are doing (for example, Tokyo R246). Take over the pace car and try to cross the finish/start line before the pace car does. However, on the rally course license tests/tracks, you may not be able to see where you are going due to the dust given out by the pace car. But, it still helps you to get at least a silver trophy.
