Yes , as a teenager though . What can I say at that age , it ' s not like there are a ton of private places to mess around in . A darkened theatre did the trick . <| sep |> I use parity CP , and know 19 nonparity EPs so far . I would not recommend doing bottom then top layer for EP , since many times you will have something like WW , which would require you to do two parity EPs . Or you might have a UU , which is really fast to solve at the same time , but slow to do one at a time . I think it is way more efficient to solve both layers at the same time , even if it is with algs like adjadj , oppopp , or adjopp . To start learning more EPs , decide if you want to use Parity CP or Cubeshape Parity . If you do plan on learning those , there is no point in learning a bunch of pairty EPs . If you decide to use the standard approach , check out Brandon Lin ' s tutorial on important EPs herets 9 qk 1 zfQT 8 . After these , just start learning the ones that are most likely to show up .
