There are four types of Schools in Grand Theft Auto: San Andreas. Each school trains the player in the best way to use the associated skill, and completion of all schools is required for 100% completion. They are listed below, along with links to their respective pages, providing full details. Schools are marked with an S on the map.
The schools operate on medal basis. In order to get a bronze you have to complete lesson with 70% to 84%, 85% to 99% will give you a silver medal and completing a lesson with 100% will give you a gold medal.
