I learnt Full PLL and the OLL algorithms embedded in them... now I've gotta learn full OLL!most OLL algorithms have a bunch of triggers i them. Familiarize yourself with these triggers: (R U R' U') (R U R' U) (R' F R F) (U R U' R')
(R U2 R') an their mirrors and OLL will be a breeze. Much easier than it looks.
edit: most people don't learn full OLL until they average around sub 15 seconds. Start with 2 look OLL and PLL before learning all the algorithms
