What are my chances???

<p>My name is Dimitrije and I'm from Serbia and Montenegro (ex Yugoslavia).
In short. My biography:</p>

<p>I'm 18 years old and I'm the 4. grade (that's like 12th grade in American high schools, senior year) in Mathematical high school. This is the best school in my country (so it's high competitive school). My GPA is 5.00 out of 5. Rank top 10%. I was a member of Serbia and Montenegro team at Balkan Mathematical Olympiad in Romania 2005 and at IMO in Mexico 2005, but I didn't win any medal.</p>

<p>Last year, I was first at National competition in Mathematic.
I have been the best in my generation at national informatic (programing) competition for last two years, but there were some students who are older and because of that I won 1 silver and 1 bronze medal on national competition, and 1 bronze on republic competition.
Physics (02-04): 2 sliver, 4 bronze
I'm the only one in my country who participated on three national competitions.
I didn't work Sat yet, but my calculations are
SAT verbal 600-700 , math 800, writing 600-700.
SAT subject physics 750-800, math II 750-800 (but both probably 800),and I didn't decide what is my 3rd subject(world history or chemistry)!!
I have trained basketball for 8 years in local club, tennis (2 years), swiming (1 year) and i'm in school basketball, soccer and handball team, and I also know to play table tennis. I'm also a member of school chess club (3 years)and debate club (from the begining, so it's 1 year).
I have learned French for 4 years in my elementary school!!!!
I took 2 seminars at petnica science centre (physics)
500+ hours of volonteer work.
I want to study engineering, economy, computer science or math, BUT you tell me as I want to study math.
I don't have enough many to pay, so I need the scholaship.
Please, tell me what are my chances at Yale!!!</p>

<p>Thank you.</p>
