Once you've obtained your real estate license and you're actually in the field, you'll probably have many moments when you say to yourself, "Why didn't I learn that in class before I started?" You got the basics of the business down in introductory courses, but situations involving clients, contracts, or how to manage your time always arise that require deeper knowledge and skill to solve. The National Association of REALTORS offers continuing education courses and designation and certification programs that can help you develop more expertise.
