<p>I’m working on my Princeton application now. I have done substantial research and want to submit a recommendation letter from my mentor. However, on Common App, Princeton only has spaces for two teacher recommendations. Is there someplace in the Princeton portal once I submit my application for me to put my mentor’s rec letter? </p>
<p>Also, I doubt there’s another spot somewhere for a third teacher rec letter, but I have another letter that I would very, very much like to include. I know it’s a lot of rec letters :P</p>
<p>Why not ask the Undergraduate Admission Office at Princeton directly? In all probability, they might ask you to have it e-mailed/couriered/faxed to the Office. </p>
<p>Also, if I may ask, what is your research about? :)</p>
<p>Excellent point! haha I’ve done 3 research project.
At Nasa Langley, I researched for correlation and ties between infrasonic frequencies and aircraft wake vortices that destabilize planes in flight. The data will be used to increase airport throughput of aircraft. A new group took over the funding about 5 months in and made it proprietary… So, I had to find a new project … government. gotta love them.<br>
Then I did research with a schumann resonance sensor. Schumann Resonance is a weird set of e&m frequencies due to lightning strikes that reverberate between the earth’s surface an ionosphere. The sensor can detect rocket launches, solar flares and anything electromagnetic.<br>
Now, I’m at a uav and drone company called Bosh Global Services doing satellite contour throughput and link quality testing. We’re comparing different vendors’ transmitter-receiver systems through an inmarsat-v satellite. It’s awesome. I had no idea what was going on when I started. Going well now though!</p>
