Passing the exam is a huge leap in the right direction toward your new career path. Next step get your license and figure out where you are going to hang it. Think about working for/with one of the top producers in your area and learn the ropes from someone who is a proven success. It will be a win/win for both you. Best of luck!
You can't complete the licensing process until you select a broker to work with. They take responsibility for you. No one can operate as a real estate salesperson in California without a broker. Your application for your sales license requires the broker's signature and you're not legal till you're license comes in the mail.
Don't worry, if you choose one firm and decide to move on to another, it's a fairly quick process to switch. But you should investigate the options and decide what kind of workplace you'd prefer.
For what it's worth I chose to bypass all the big firms in town and work with a small shop with a real estate attorney as broker. That works for me.
