You can play ranked rounds through stroke play (set it as ranked) and tournaments. As long as you finish the round it will count as your ranked round total. After 5 ranked rounds you will move to Amateur. If you play well enough at amateur and reach the required ranked rounds for Pro you will move to Pro tier. I don't have the list of requirements in front of me but if you search the forums they are out there. As you move up the rankings you will have more appeal to the top CC's.
Good luck and let the fun begin!
