Broker vs Managing Broker

[Vlad Kuzin]

I am just starting as real estate investor, and only had few deals done. I am looking for freedom to access MLS information and have MLS key to see properties, so I am thinking to get license.

Since I live in Seattle WA, I wonder what is the difference between Broker vs Managing Broker? Should I just get regular Broker license to get access to MLS?
I heard somewhere that Broker has to work for Managing Broker, but I cannot get Managing Broker license because I do not have 3 years of experience working in real estate. Can someone who done this before clarify which license I need.
