I was wondering if I could put Captain of my sports team, even though it is in the spring of my senior year, on my college application. I have 100% certainty that I will be the captain.
You could put “Captain in Spring”.
But how can you be sure? You could put (expected) captain.
It’s possible that spring sports may not even happen if Covid is still raging. I think the suggestion of saying “Captain (expected)” is a good one.
Have you been named Captain? If not, why do you (100%) expect to be Captain?
