PowerQuery Book Camp

[wherdzik]

Anyone know where I can do a serious PowerQuery bootcamp. I have been  using PowerQuery for a few years but its all self taught stuff and YouTube videos.  I am not sure I am using it the most efficient possible way.  Anyone got some suggestions? I dont need basics, I think I am already there, I need like the more advanced stuff.  Thanks

I followed the course  Mastering M, A Deep Dive Into the Language That Powers Power Query by Ben Gribaudo. I highly recommend the course for anyone looking for a better understanding of the M language that powers PowerQuery. It really helped me along:
