See the world! Join the virtual study group! The VSG is your chance to interact with the course mentors, and your fellow course participants. ACEM is a broad pantheon, and lots of regions do things differently. (Trust us, we know!).
More, as your study progresses, you'll find that often that the fellowship incorporates many shades of grey. Bouncing your ideas off your colleagues and the course faculty is a great way to build and consolidate your knowledge.
