I'm upgrading my license to a broker's license ( in California) real soon and I'd like to know if anyone has recommendations of a good company that offers exam preparation classes, or 2-3 days seminars, etc where they expose you to most of the questions that will appear on the licensing exam. When I google it there's a lot of options so I'd like to know if anyone has done this recently and could recommend a good class/crash course. Thanks in advance.
