Middle layer
U R U' R' U' F' U F - moves top layer piece into right middle layer position - prep work is having the top layer piece lined up with corrosponding colour (3 vertical lined colours)
U' L' U L U F U' F' - moves top layer piece into left middle layer position - prep work is having the top layer piece lined up with corrosponding colour (3 vertical lined colours)
-------------------------------------------------------------------------
Last layer - Yellow cross (prep work in brackets)
F R U R' U' F'- progression is.... scatter > reverse-L (rear right) > horizontal L (parallel) > complete
-------------------------------------------------------------------------
last layer - yellow edge line up - R U R' U R U U R
spin the U face looking for two yellow cross edges that line up in the same corner ie, green/orange. orange/blue. blue/red. red/green. if no two edge corner combos can be made use the ALG and check again.
If two line up, bot opposite, have it so that one is lined up facing you, and the other away from you. perform ALG
now spin the U face until you have two the edge corner combo. when you have it, the prep work is having one completed on the right hand side, the other on the back side. Perform the ALG and do one U spin and all 4 yellow edges should be in correct positions.

layer layer corner positioning - U R U' L' U R' U' L
find a corner that is in the correct spot, but not nessesarily orientated correclty (orrientation isnt important now).
you will have 1 or all four already complete. if you dont have complete, find a correct corner, use the ALG. repeat the ALG on that correct corner until ALL corners are correct (remembering that orientation may not be correct. positioning is what we're looking for)
-------------------------------------------------------------------------
last layer corner re-orientating. D' R' D R x2
find a corner that is fucked up. it doesnt matter which one. now have that corner front right hand position. perform the ALG until the corner is correct, ignoring the rest of the cube (it will look messed up but will correct itself when fixing last corner)
when you complete that corner, simply rotate the U face until the next fucked up corner is in the front top right position, repeat the ALG until that corner is correct, and keep going until all 4 corners are correct. once all 4 corners are correct, simply spin the U face and the cube should be complete.
