I just read through this thread and it seems like the OP has calmed down a little. I’d like to comment because I can see a bit of my childhood self in the OP. I was convinced by the time I was 10 that I needed to excel so that I would be tracked into honors classes, so that I would get into a good college and then a good medical school and then a good residency. My fourth grade teacher actually told me that if I didn’t stop worrying so much I’d have an ulcer by the time I was 12. (Although we now know of course that ulcers are caused by bacteria and not by stress).
In any case, I was one of those students who had good grades, lots of activities etc but nothing interesting that I really excelled in. It took a while to accept the following truth:
Elite college and graduate schools have a minimum standard for grades, SATs, etc to ensure that students are capable of doing the work. Once you exceed this standard you are in their pool of “eligible” students. The final decisions are made in large part in order to balance the class. If you have done something truly exceptional (like win an Olympic medal) then it is likely that you will be seen as unique and may have a greater chance of being accepted. For the majority of the rest it can be random. They try to balance for age, gender, ethnicity, outside interests etc. The majority of the class will not have something truly exceptional on their records; they will be students who are picked from the “qualified pool”. If you play the violin but they get 100 violinists that year and only one tuba player-they may be more likely to accept the tuba player.
The OP appears to have a good handle on what gets a person into the “qualified pool”. Beyond that, there’s nothing concrete that can be done. You might be a person who wins a pretigious prize but if 5 other prize winners apply the same year they might only take 2. This is a hard lesson to learn-that you can be good enough, but still be rejected. I speak from experience as the Queen of the waiting lists for medical school. I did everything right and got through all the applications, ane all of the interviews and was kept waiting, and waiting, and waiting. When I finally got in I realized that I was just as qualified as any of the other students. The only distinguishing factor I could find was that my fellow students were the most charismatic group of people I had ever met. Talk about selecting for intangibles!
I have two recommendations for the OP. First-you mentioned that you have some issues with OCD (handwashing for instance). This may be affecting how you are handling your concerns about college. I would suggest you get help before the symptoms worsen. OCD can make you more competitive and high-achieving but it can also ruin your life. It is treatable.
Second, take a deep breath and remind yourself that you will easily be in the “qualified pool” for any of the elite schools. Beyond that, you realy don’t have that much control. Spend your high school years figuring out what you enjoy doing and what you can be happy doing every day for the rest of your life. Ideally, spend your first couple of college years doing that also. Find your passion and then figure out how to make money at it (and if you truly find what you love to do you may find that the money is no longer as important). Get a well-rounded education-this is the best time to do so. Play the violin if you love playing and stop caring about what others think. Realize that you have all the time in the world to decide what you want to do. Now is the time to try different activities and figure out what you like doing. Don’t lock yourself into a path too soon. Don’t waste your high school years stressing about the future. Look at the list of mathematics award winners noted above and see that many of them did not go to traditional “tech” schools.
You are obviously smart and you obviously have musical talent. You simply have to realize that if you are going to succeed in life the things you are obsesssing about (like which college to attend) really really don’t matter much. The cream will always rise to the top. The kind of people who are impressed by a “name” school are not the people you want to impress.
