State law requires that you complete an approved total of 90 hours. The first Unit I(First Year Sales) class is a total of 60 hours and Unit II(Final Sales) is a total of 30 hours. The Unit I class will prepare you for the South Carolina real estate exam. After completing the first year sales course, you would send your application to the LLR - Real Estate Commission, then make an appointment to take the state exam. The 30 hour Final Sales class can be taken before or after the exam but must be completed in order to obtain your license.
