@vrmeenrajan To me it sounds like you are a great student and a great kid. I am very proud to have two daughters who are similarly smart and responsible.
At some level you need to do your best, and know that good opportunities will come to you.
When it comes time to apply to universities, my suggestion is to apply to UF, apply to Brown, and apply to a few other universities in Florida and probably a few other top schools. Then see where you get in. If you get into Brown, then see what it will cost and see what your father feels about it at the time. You might end up at UF for undergrad. If you do it is a great university and you can do very well with a degree from there. You will graduate as an adult who gets to make her own choices. On the other hand, you might find that you father ends up telling everyone how proud he is that you got into an Ivy League school, and suddenly discovering that he thinks that this is great. You will not know what will happen until it happens. Either way you will have great opportunities.
In the mean time keep your grades up and live responsibly. Try not to fight with your dad. None of us dads are perfect – we do not have much experience with being a dad.
To me it sounds like you are a great kid and I think that this will work out one way or another.
Best wishes for all of this.
