How to get licensed?

[Antonio Bodley]

How and where do I go to get this license for MLS access? I hear there is a cost involved. How much does it normally cost to get licensed for this? I am assuming there is a test involved to get this license. Right? I just need something that will provide me with accurate or close to accurate values of these homes in my area. I am only seeking out this MLS because so many others talk about how great this tool is compared to those websites like Zillow and the rest. If I wanted to just signup for MLS access and pay the cost for that, where would I search for that? Thanks for your help.
