I suggest u go and learn intuitive f2l in badmephisto video on youtube..learning algs is hard..last time I spent almost 5 days of memorizing f2l algs and end up with a result worse than the beginner method. Then not long ago I watched badmephisto video and learned f2l in 1 day..it really helps a lot, my average from 57.25 drop to 43.71 in with 6 days of practice for the intuitive f2l.
