Notifying colleges of awards past application submission

I submitted my application for Early Action to Northeastern and WPI. I recently got two pieces of art accepted into a juried regional high school exhibition at UMass Lowell and received funding from my high school’s school board to prototype/go further with a product that deals with quantitative light-induced fluorescence and etc. Are these things I should email colleges about past submission dates?

Why not? Just a quick E-Mail note to admissions asking them to add it to your file. If it’s too late no skin off your nose.

I would email your regional admissions officer (should be able to find online) with the updates and reaffirm your interest in the college.
