hey I'm not a beginner i average around 20 secs on 3x3 and just got a 7x7 does anyone know how many parity's there are on a 7x7? And if so what are there algorithims.

when should I learn l2c and l2e algs I avg 1:50 on 5x5
Any time you want to.

Treat L2C like F2L (or F2B, since you're a Rouxer): look at the algs to make sure you know what the efficient solutions are, but learn them by looking at how the pieces split apart and join together.

Priority for L2E algs should be (from highest to lowest):
1. all basic slice-flip-slice cases (including the double midge flip)
2. r U2 r U2 F2 r F2 l' U2 l U2 r2 (execute as r U2 r U2 x U2 r U2 3r' U2 3r B2 r2)
3. r2 F2 U2 r2 U2 F2 r2 (looks like PLL parity)
4. (F U' R U') (r2 F2 U2 r2 U2 F2 r2) (this case is missing from many alg sheets, including Speed Cube DB at the time of writing (!))
5. r U2 r2 U2 r' U2 r U2 r' U2 r2 U2 r and the inverse (diag checkerboards; this is the only L2E case where the best alg happens to be rU 2-gen)
6. all of the rest

I use yau and some of those algs distrupt the cross is there a sheet for l2e with cross?
