This business is really about mentoring, working in the field, learning from mistakes, experience, research, licensing and asking for help when you need it. You'll learn more in real life than you will from the books. I've found that after I got my Real Estate Salesperson's Licence, they taught me nothing about how to sell real estate and I learned nothing at school about the anatomy of a purchase. These things I learned from experience.
You can start with a Broker's licence and add everything "a la carte" or "designations". If you are heading towards commercial sales, you would get your Broker's license, then go back for a CCIM. Here is a list of designations you can get:
