You only named five Ivies in your post. You need to sit down and do some thinking about what you want in a college. (“Ivy” isn’t an option). Right now, you don’t seem to have any criteria other than prestige. What do you want to study? Where do you want to go to school? Do you like a green leafy campus or do you want something urban? Do you want a preprofessional environment or are you looking to a more classic college experience?
Brown and Penn are both great schools but they are very different, location, size, feel, type of student. While a student can apply to both, ask yourself what draws you to Penn and what draws you to Brown?
Once you have a list or description of what you want in a college, then the search can begin. Start at the bottom. Picking the safety is the hardest part of the search and it will take work. Find two schools with at least 50% acceptance rate. These are schools your parents can afford, you are assured admission, and you will be happy to attend. There are hundreds of schools - you will find schools you like but only if you put in the effort. Do not settle for the default state school if you do not want to attend.
Another way of looking at safety schools is to find schools where you will automatically get merit aid based on your stats. I call them “goodies” schools, because these schools will give you money to attend. Your stats will be well within the top 25 percentile, probably top 10 percentile. These schools will not be the prestigious ones but they are well known and respected within academia.
Once you have two safeties, then it’s up to you. Lots of reaches, knowing that you will likely be attending one of the safeties (remember you are guaranteed admission), or a mixture of matches and reaches as well as the safeties. Pick the matches using the same characteristics you used for choosing a safety.
Picture the schools on a ladder. You are looking for or at a particular type of school. You want to find schools with these characteristics but with acceptance rates of 50+%, 35-50%, 20-34%, and the teens and single digits. Sure, you can knock out the middle rungs but the climbing is pretty hard.
I echo using rolling or EA to safeties or low matches. Knowing you have a college acceptance before Thanksgiving is definitely an ego boost even if it’s a safety or match. This boost is necessary because if you go the “lots of reaches” route, you will likely get some rejections (they hurt more than you would expect, even from HYP). Also, it’s just nice to have your first response be a positive response.
