Do you feel comfortable telling us a few of the schools that you were accepted to? Are they affordable?
There are a lot of very good universities in the US (and just as many outside the US). Students often get fixated on a few famous schools. However there are very strong professors and very strong students at a very wide range of universities, and once you get to class you will discover that is true where you are. Once you graduate and get a job you will find that you are working with students from a wide range of universities and no one cares where you got your degree.
I am generally skeptical about applying to 17 reaches. One issue is that it is difficult to imagine that 17 reaches are all a good fit for you. Another issue is that to get accepted to “highly ranked university” you should be able to clearly articulate why “highly ranked university” is a good fit for you, and I cannot imagine being able to do this for 17 different schools.
One daughter graduated a few years ago with a bachelor’s degree from a university that is not quite in the top 100 in the US, but is “top 50” for her major. She is headed in September to a graduate program that is “top 5 in the world”. She is able to very clearly articulate why that specific program is the best one for her (and can do this while ignoring the ranking). I think that this helped her chances of admission. If you get to the point of applying to graduate schools in a few years, similarly you should know which schools are a fit for you and why.
Regardless, you are wiser, and it sounds like you are headed to a very good university in September.
