Odyssey of the Mind as an EC?

First I’ll give you a brief overview of what Odyssey of the Mind (OM) is: Its an international problem solving competition, where teams must choose a problem which could consist of designing and building a vehicle to perform tasks or respresenting solutions to real world problems and questions in a creative way. There are many levels of competition with the final being World Competition.

Odyssey of the Mind has been my main EC since 2nd grade and have been on the same team ever since, we meet 4-15+ hours a week depending on the time of year and have had some success:
1st in regionals 2x
3rd in NYS ( most competitive state for OM)
1st in NYS
2nd in US
5th in World

I’m wondering if this will be a really good EC to accompany my undergrad architecture applications as it revolves around creativity, designing, and building and I have success in it

Sounds like a great EC (problem solving, teamwork, presentations, etc.) and really shows the adcoms who you are and what you like to do away from the classroom.
