The final three stars can only be acquired by earning a perfect 100 on every level. If you do not succeed, you will be unable to proceed. There are currently 25 such programs, each with its unique set of problems. There is no software available that can perform these tests for you. To get three stars, you must complete each level in record time. When time is of the essence, adopt a course of action immediately away. Racers on an obstacle course may yell at one another from behind their protective helmets before plunging headfirst into their vehicles.
