Awards/Achievements

I have legacy which counts for a lot at Lawrenceville so hopefully that will also help a lot.

My SSAT overall was a 99% and I got a 99% in math, a 98% in reading, and a 92% in verbal.

My essays and interview went quite well and my recommendation letters should be pretty good.

So, do you think I have a chance?

Thanks!

Yes.

Good chance.

Lville legacy acceptance rate is about 60%. Your chances look good.
