Your question is quite straightforward

Cat 4 = New riders
Cat 3 = You need to gain 10 or more points whilst holding a Cat4 to get a Cat3

Cat 2= Lot harder, you need to gain 40 points whilst holding a Cat 3 to get a Cat 2

Cat 1 = err unreal pace = You need to gain I think 200 points whilst holding a Cat 2 licence

Elite= Dont worry you would already have found out your that good


Also you have to retain a certain amount of points each season after gaining each licence.
