Lawrenceville senior here. If you applied when I did (2018), I’d say you’d probably get in, but admissions has become so wildly competitive at this point that I can’t even tell.
Make sure to ace your interview—it’s your one chance to make a direct impression on the person who will eventually be advocating for you in committee. And yes, the financial aid question is important; unfortunate, none of your schools are need blind.
If you have any questions about Lville, let me know!
