I just "finished" learning how to do F2L intuitively and now I need to learn how to do OLL and PLL, but I'm lost with so many formulas. I know learning one at a time is what you'll most likely suggest, but how would I go about doing that if the probability of me falling in the same case twice is low? Any help is appreciated.

The method I use for the last layer is to first build the cross, then place corners in the right place and finally flip them so they face the right direction.
