Ordinarily though, my opinion is a more rigorous high school will better prepare students for the college experience. My daughter worked her tail off to stay in the top 10% of her college prep high school. But, unless you were #1 or 2, the school only reported percentile rankings, not individual class rank.
As an aside, If your daughter is already interested in IT, I’m not sure why you are focusing on the Ivies. Cornell and Princeton have solid programs but MIT, CMU, Stanford (reaches for everyone). UT, Georgia Tech, Michigan, Purdue, RPI, etc… should be on the radar when the time comes.
