I am assuming you are boarding. Loomis had over 2300 applicants this year. For 9th grade there are 30 spots each for boarding girls and boys. 10th grade they add 15 each gender. There are probably 7-10 each for junior year. If you do the math, factoring in %30 day students, it comes down to approximately 800 applicants for each gender of boarders. I have no clue as to how the 800 breaks down, but obviously very competitive either way.
