What Are My Chances Of Getting Into: Cornell,harvard, Georgetown,nyu,unc,duke,dartmo… And Columbia?

I have a 3.94 so far in the first semester of my Junior year, I’m a junior now. I have an A- in AP Chem, an A in AP US History, A in Pre Calc Honors, A in AP US History, A in English Honors, and an A in Intensive Italian (three years of Italian in 1).
In my sophmore year, I had a B+ in Honors Chemistry, A in Trig and Alg 2 Honors, an A in Global Studies 2 Honors, an A in English Honors, and an A in Spanish 3.
In my freshman year I was extremely lazy and my grades werent as good as they should be: B+ in Geometry, A in English Honors, A in Global Studies 1 Honors, A in Biology Honors, and a B+ in Spanish 2.
All of the grades listed are unweighted and have no sort of cushion. I only listed the grades of 5 core classes(foreign language, social science, lab science, English, and mathematics), as I read somewhere these are the only ones that truly matter. Regardless, I had As in them anyway. The GPA I listed in the beginning is the GPA only taking into account my unweighted grades of my core classes.
I am in Key Club, Chem Club, National Science Honors Society, Italian Honors Society and the tennis team. Tennis is my passion and I play 5 days a week and am state ranked. I’ve been on varsity since 7th grade playing in the 2nd highest spot. I’ve played national tournaments as well as the high school state tournament for doubles.
I plan on playing college tennis. I have yet to take the SATs, but I have been studying for at least an hour everyday, and I take the Princeton review course in March, with only 4 students in it. I plan on taking the May test. The only school that e-mailed me was Dartmouth out of the ones I’m applying to.
Also, I’m an African-American male from Newburgh, NY (dubbed the murder capital of New York). Also I’m in the top 3 percent of my class in Newburgh Free Academy, a school so large in terms of population it had to be split into two campuses.
Also, my brother graduated from Harvard for his bachelor’s and Georgetown for his law degree. He’s an Olympic athlete as well, check him out! His name is Samyr Laine. I thought it would be important for legacy since Im applying to both schools. Any input would be helpful, my parents are confident in me, but Im not so certain, due to the fact that that I’m the only one in my family without a bachelor’s degree and at least one Master’s Degree (My parent’s are Haitian immigrants).
I’d appreciate a response from anyone who doesn’t love me haha
Additional Details
Also, I believe I should get around a 1900 on the SATs. I’m going to take the SAT 2 chem, physics and History exams and am confident that I will score fairly well in accordance to the standards of the schools I’m applying to. I think this should be easy enough for people to read.
