WORRIED...What else should I do?

<p>I am currently a junior and I am interested in becoming a emergency doctor. My top choice is UVA and William and mary and also UNC...
so here is the facts:
GPA:3.7 going to be 3.8 by end of this year
currently in the math honor society and is entering national honor society next year
I currently am taking 4 ap courses: calculus, chemistry, u.s history and mandarin
next year I be taking 4 as well: physics, computer science, statistics, euro history
I be taking my sat soon so that I don't know but I am striving for like a 2070-2250?
I am also taking 3 subject test next months: Math II, US history, Chemistry I am hoping all of them to be above 700s.
I am also in band...but that's my only extra curricular due to my band is year around. I tried freshmen year doing tennis and band at the same time it got my first 68 on a test so that was it for me....
I am working all summer to gain up on my community service hours.
So yea these are the facts about me....I guess it only tells u about me academically not personality but I will definitely try to write the best essay lol.</p>

<p>I am just really really worried. I live in New Jersey. There are plenty of smart kids in the world. I am not looking to get in yale or Harvard or anything but my top three college choices are also really competitive. I really really want to get in. I want to get other's opinion on any additional things I should look into doing. Senior year is right around the corner and frankly I want to be the kid that cries when they get their admissions letter because they are going to their dream school. I am super nervous. My mom has warned me and she is always looking on the opposite of the bright side. She said if I can't get into any of those I might need to try TCNJ even there she doesn't believe I could get in. I have not taken the ACT. I really think I should take it but my mom thinks college admission looks down on it bc it is an alternative if you are bad at SATs. I disagree with her. I just don't know. Is it worth for me to take it? I mean it is more sciencey. I am not sure if I am overthinking it or just need to relax but some tips would help :) thank you so much</p>
