The course has 16 people enrolled spread across the world. During the week you read tutorials and complete exercises. Over the weekend you and your partner let your trained agents compete at a game in a tournament style competition. This week it's Othello.
The course material is top notch and you have office hours each week to discuss with the folks running the course.
Other courses either don't have this peer to peer interaction or run for too long.
Even though its been a lot of work to go through this course, I can't recommend it more!
I started doing Brazilian Jiu Jitsu. As a result, I drink way less, I'm in a better shape, and can defend myself. I know that drinking will have a negative impact on my performance and that is enough to keep me away from booze. I've also noticed that refusing to drink in a social setting is way easier, both for me and the social group I'm in.
It doesn't have to be Jiu Jitsu, it can be exercising in general.
I use zapier to sync different calendars to a single calendar. I believe they allow 1000 zaps free per month. I'm way under that limit. Highly recommend!
