This is updated version of New Super Mario Bros. Wii Any% Strat Tutorials You can see beginner, fast and optimal strats from this series. This Strat Tutorial series has every single level from Any% category, except 8-7 and bombless.

Optimal strats aren't always "optimal" because I'm not a TAS bot. Also, there isn't optimal strats in 5-GH, because it would be just same as fast strat, but small timesaves during the level.

Some of the strats might be too easy or hard, so you can mix the strats and make strats what are the most consistent for you.
