Beginner DJ Course question

Hello everyone :)

I very recently grew an interested in learning to DJ when one drunken night I was playing around on my friends controller and enjoyed myself a lot.

I purchased a Traktor S2 MK3 and have everything setup and have been enjoying myself just messing around with transitioning between songs.

I would like to learn how to improve and better my skills and was looking at an online paid course that I was wondering if anyone had some experience with?

TRAKTOR - BEGINNER ONLINE DJ COURSE - through wearecrossfader seems to cover a lot, any thoughts?

If there is something better or any tips please let me know and thank you for taking the time to read :)
