Any suggestions on format/ how much to include and if it should repeat what was already stated in the 10 activities?
I think it is best NOT to give admission officers extra things to read that say nothing new. They have a lot of applications to read. If you don’t have some unusual need to include a resume, it’s best to leave it out of your application. Use the space the app gives you for activities/additional information, etc.
It is a good idea to have a resume available to give to teachers writing you a recommendation, to an interviewer, to include with scholarship applications, or to send to a coach or professor you are communicating with; etc. Include it with your application only if it is specifically required, or if it necessarily includes information not found elsewhere in your application.
