I think that pro "teaching" would fill someone's ego more then it would help newbies learn anything.
6 months ago I played only shopper. Then discovered boom, aerial, big rr, ttrr, battle, darts..
And improving each day just by playing. So, who wants to learn - it can be learnt pretty fast.
Play some big rr against sid, some boom vs husk, battle race vs wally and kory... and you'll get why ppl call them pro's.
Tutoring school is nerd and totally not necessary
