Hi GrindingNajra,
I'm not sure what you mean by "course".
There are the MTT strategy articles, but they're not organized into courses.
Check out videos by Honigmund38 who covers both Sit & Go and MTT formats (10 videos)
Also videos by AaronLambert would be useful. Some of them form a series on the 180-man Sit & Go MTTs (25+ videos)
And last but certainly not least are all the videos by Collin Moshman (40+ videos)
All of the above links are searches of the video catalogue by author, and list only videos silver and below
You might need to filter through to find content you want, but that should keep your study time occupied for quite a while.
Some of the videos are of live coaching sessions.
I'd be interested in reading what other suggestions members have.
Best of luck :gl:,
