From your other thread (or one of your other threads) I see that you are doing very well in high school. Good work!
In addition to the excellent advice that was given in the other thread, I have a question: Why is Stanford your first choice school?
This might seem like a dumb question. However it is in fact important. Top ranked schools such as Stanford are very good for a wide range of majors. However, they are not all the same, and none of them are a good fit for all very strong students. From a distance “Stanford” is a name that we associate with a famous university. Once you are on campus, the reality sets in. [One note, I got my master’s there and loved it, so it is at least conceivable to me that it might be some student’s first choice.]
Top schools are looking for students who will be a good fit for them. Given the very high four year graduation rate for Stanford, it appears that they do a relatively decent job of this.
As one example, Stanford is academically very challenging and is on the quarter system. One plus of the quarter system is that you get to take a lot of classes during an academic year. If you like a class you might take the next in the series the following quarter. If you do not like a class, or if you want to only get a moderate amount on that particular subject, then you only take one quarter’s worth and are on to something else the following quarter. However, the end of the quarter comes up faster than you might expect, and you better be caught up on all of your classes or finals might be upon you faster than you are prepared for. Personally I liked the quarter system, but this might have been partly because I was there as a graduate student and was older and more inclined to keep ahead in everything.
When I was at Stanford I found myself spending many Saturday and Sunday afternoons doing homework. This is a big part of “being caught up”. If you were to spend 6 hours on a Saturday solving one very tough problem from one homework sheet, and supposing you succeed, would you be thrilled that you were able to solve it, or would you feel that you just wasted your Saturday afternoon?
Stanford is also a long way from New York. Attending Stanford also implies flying out to California (probably San Francisco, possibly San Jose) and back. In December and January you are not going to run into snow-related delays in SFO, but you might run into snow-related delays in New York. How do you feel about the flights back and forth? If you have some sort of emergency (get sick or have a nasty breakup with a girlfriend or boyfriend) then you parents will be a long way away. In contrast, you have great schools in New York state which would be a lot closer to home.
Also, in your other thread I noticed the small note “(premed)” as one possibility. By the time that you get to medical school, if you get to medical school, it is likely to cost over $100,000 per year. If you want to keep this as an option, you should budget for this up front. Doctors are relatively well paid, but $400,000 in debt is HUGE even for a doctor. Some doctors are still paying off their debts quite far into their careers. Can you afford four years of Stanford plus four years of medical school without taking on a big chunk of the cost as debt?
Personally I think that the first thing to consider in creating a university list is safeties. You should pick at least two safeties that you know you will get accepted to, you know that you can afford (preferably with no debt, and with some college money left in the bank or 529 if you might be premed), that have a good program in your intended majors, and that you would be willing to attend.
Once you have your safeties picked up, now you have the luxury if thinking about other schools that you might prefer to your safeties.
And if you have solid safeties, I do not see any harm in “spending” your REA on Stanford.
I also would not worry about how many other students from your high school have gotten into Stanford or Cornell or Harvard or any other top school. I think that the right approach is that you do what is right for you, and assuming that you pay attention to budget and apply to safeties and do well in your classes and treat people fairly, it should work out one way or another.
I also agree about dropping the “dream school” thing. There are a lot of very good universities.
