Reply to DJ School...Over-Rated...?

I'm in India at the moment, doing an intense 1 month DJ Course. I'm learning all the basics; Beat matching, cue-ing, pitch bending etc.. But I want to enhance my skills, to be better than I am.

Is it mandatory for me to go to a DJ School? Say, Dubspot (New York), to do an advanced DJ Course? Or can I get better and better by just practicing and watching vids on youtube, or watching guides on the net.

Price is no an issue, just tell me whats best. I really want to get better.
