im learning full PLL and to be honest im getting mixed up ..i have learned 8 over the past month...and i still get mixed up...im practicing them and straight after...i can do them easy ..but the next day i have to get the charts out...there are only 1 or 2 that i know properly....those who say i learned full pll in 2 weeks are bluffing....there is just no way to remember if it starts with an R or an R; that quickly..recognition is easy ...but each Pll has so many moves and is similar to others...that you just need to learn them and then keep at it until you dont need your charts any more....its frustrating but worth it.
