I was clueless a year ago, thanks to my parents and their support, I am much better prepared for this college thing.
First and foremost, know what you want to pursuit. I see it often, “I want to apply to Dartmouth but not sure what major.” If you are not sure what major to study, how do you know Dartmouth is a good fit?? I want to be an engineer, so I started researching engineering school. I compiled a list of best schools, then applied personal filters. Maybe its too far, maybe its too expensive, maybe its too rural, maybe its too cold, maybe your ex went there. Whatever the reason, so be it, cross those out. Research to see if those school fit you academically. If you are in the 75th percentile, its a match. If you are in the 25 percentile, then call it a reach. Cross out schools where you are less than 25. You want a list of “potential fit” to visit and compare. Research grants and need base scholarships. They could be the difference maker.
Visit the damn schools. I cannot stress this enough. I have a completely different lists before and after visits. Check the campus vibe, see the weather, feel the student spirit. Understand that they are all similar, just that one will fit you a bit better. Let your parents have their input and ideas, but it is your choice. If you dont let them pick your clothes for you, dont let them pick your career for you.
Check out the application choices. ED, EA, ED2, RD and form a strategy. Research each school and see your chances. Johns Hopkins and Northwestern admit majority of students thru ED, so understand your chances of RD. Pick one minor reach for ED and a few EA as fall back. If you are a match for one school, doesnt mean you have a good chance in the RD. Each year 10s of thousands apply to Ivy leagues and such with 1500+ SAT/ACT and 3.9 GPA that are rejected. Imagine competing with them at RD with your match school.
Write a good essay, but understand what they are asking for. Go bold for your reach, sorta like a hail mary. Go conservative for match. Read different essay advices and have a voice in it. Be different with a positive tone. Do not ever ever ever ever ever ever use the essay to say your had a rough childhood or Chinese parents. Do not play the sympathy card or race card, unless you are applying to the schools I am applying to.
If you are Asian, give yourself a -10% chance. My Chinese parents call it the egg roll tax on college admissions. If you are in state, legacy, first gen add 5%. If you are black, congrats, add 15%.
Dont assume anything, nothing is guaranteed. Read many of past admit results and see many were disappointed with how cruel this thing may become if you let it.
Good luck.
