This real estate sales course consists of 40 hours of instruction which must be completed before taking the real estate state exam, which you have two years to take. A real estate sales candidate must be eighteen years of age and to be eligible for a real estate sales license. Our goal is for you to pass the exam the first time — but, if for some reason you don’t — you may retake your class series for FREE!* You have up to two years from completion of your initial course to pass both sections of the exam.
