Need a little help solving the last part of the Rubik's Cube puzzle? Permutating the last layer could be tricky, and could get you back to square one if you don't know what you are doing, but don't worry, you'll be able to solve that Cube in every possible PLL situation.
Check out this video tutorial on how to solve the Rubik's Cube with the N Permutation. If you take your time and memorize this step, along with the rest of the permutations for solving the Rubiks Cube, then you should have no problem solving it, or possibly even speedsolving it.
