Hi, I am part of my school's Science Olympiad Team and I participated at Princeton University's Science Olympiad Invitational where I placed 11th for my event out of 51 other schools. I, unfortunately, did not win an award however and I needed 6th place to win an award so I do not know which tier extracurricular this will fall under in the non-art competitions so I would really appreciate it if you would let me know what it is. Thank You!
Tier D seems correct to me.
That would be Tier D... unless you won your event, you won't get much recognition.
