Should I email the elite universities I applied to (Princeton, Stanford, etc) with these updates?

I’m an international high school student who goes to a british curriculum school in qatar (in the middle east) and I needed some advice on whether I should update my colleges with some recent updates.

The updates:-

I got an international award from an international mathematics challenge with which I attained a full scholarship with 10 other students across the entire world to attend Pisa, Italy to do some mathematical calculations regarding the leaning tower of Pisa.
I have been working with a professor from a local university on a research project for about 1 and a half years, and we are near the completion and are looking to publish the paper. It’s related to S. Hawking’s idea of 1/5 light speed acceleration using lasers. Note: I did mention this but didn’t mention its near completion
I won the best drummer award at my country’s national music competition
I recently started my own non-profit organization with the help of 2 of my friends and my dad. We help uneducated children earn a valid education throughout the world. We’re going on a trip to Nepal soon to hand children loads of mathematics related course books to aid them in their education. We earn our money through fundraisers throughout the country.

Most if not all of it hasn’t been put into my common app or anywhere and most of these colleges didn’t have an upload thing on their portals so I couldn’t upload an update resume. Thank you for the time in reading this. Do you think I should email these colleges with these updates? Would they be of any significance since decisions are literally out in 2-3 weeks?

It’s certainly can’t harm.

It is very late in the game for updates – it may not help but it can’t hurt. If any school allows updates through a portal I would do that, otherwise email your admission officer.

It won’t hurt. But given that it’s March 17th and decisions are coming out in less than 2 weeks, it may not be considered. If the decision has already been made, any update is unlikely to move an application out of a reject pile. Some further recommendations:

Not worth an update. Even before the recent admissions scandal, this would be viewed as a self-funded (or more accurately, dad-funded) exercise. Regardless, AOs assume you will continue to develop ECs; they don’t need to know ones you started yesterday.

Not worth an update. They assume that it will be complete at some point; the exact projected date of completion is minutiae that they neither want nor need.

Send the math award MOSTLY

Send the drummer (if it ranks you as #1 nationally)

Starting a non-profit at this stage won’t impress
That your paper is nearly ready for publication won’t impress

“regarding the leaning tower of Pisa.”

Thought I read that the tower is leveling out… and won’t be leaning.

Yeah I probably might just send only those, thanks for the help!
