you have to get a gold cup on every course of every class also you need to get a 3 star rating on every course you do this by avioding obstacles and stay in 1st place for the longest time possible.
you need to complete all time trials in a record time beating the ghost data (ussally 20-25 seconds faster then the original computer's ghost data).
you have to have a super Mario galaxy game save on your Nintendo wii then play 50 of the 50cc cups to unlock a character named rosalina.
once you have done the above you should of unlocked every character and vechicle then you need to have a broadband connection and you need to play a lot on Nintendo wi-fi as you only start with 5000 points and to be the best you need to have 15000 points so it will take a long while
this is how you become the best on Mario kart wii.
For rank A (or higher), you need to not fall off the stage more than once in the whole cup, you can't bump into things more than a few times, and you have to get 1st (high chance), 2nd (moderate chance), or 3rd (low chance) in the cup. I hope my answer helped :)
