While perusing LOL Reddit Summoner School, I found a link to this streamer and some coaching sessions he had done with players right around my level (Silver).

The content centers largely around decision making which is definitely something I struggle with around jungling where your time is super important as you constantly have to make decisions around farming, ganking, and counter jungling.

E.g. If you are blue side and you've just taken dragon and you've got jungle camps up on both sides of your jungle where do you go? Answer likely Top because Rift Herald or Baron are the key objectives now aside from towers if they are still up.

Or where to place wards before committing to a gank as if you don't know where the enemy jungler is or they are able to converge before the gank has played out, you may be in for a nasty surprise.

Good stuff presented in a way that I found easily digestible.
