What are my chances?

Hey everybody,

I’m a junior, and although my testing etc. is not complete yet, I was wondering what my chances would be to the following schools: Duke, Northwestern, Georgetown, UNC-Chapel Hill (probably a given), using my current scores. I am taking the SAT again next month, so I will probably expect marginal improvement.

Objective:
SAT I (breakdown): 750 (Math), 710 (Critical Reading), 780 (Writing)
ACT: Not taken yet
SAT II: none yet, but most likely US History, English
Weighted GPA: 4.28 (only sophomore year, but probably 4.39 after this year)
Rank (percentile if rank is unavailable): top 25% (school only ranks by quintile)
AP (junior year): US History, Physics 1, English Language and Composition
Awards: Day of Recognition (with certificate) from Governor on behalf of state, Geography Student of the Year, National Society of High School Scholars, NHS (most likely), AP Scholar (most likely)

Subjective:
Extracurriculars (place leadership in parenthesis): Boys Service Club (Treasurer), Pre-Med Club (Officer), School Admissions (Ambassador), Youth and Government (Statewide Committee Chair and Candidate for Presiding Officer), global peer-reviewed science publication for high school students (Senior Editor and help lead editorial staff), Yearbook (Copy Co-Editor), Computer Science Club, Varsity Tennis team

Job/Work Experience:
Volunteer/Community service: Work in school library and in a school for special-needs children
Summer Activities: state-funded science research program (last summer), Governor’s School (most likely)
Teacher Recommendation: both should be excellent
Counselor Rec: my counselor knows me very well and is helping me in this process

Other:
Applying for Financial Aid?: probably not
Intended Major: Global/Public Health, Public Policy, Biology
State (if domestic applicant): North Carolina
School Type: smaller school (~80 people in class)
Ethnicity: Asian (Indian)
Gender: Male
Hooks: participated in National Spelling Bee twice? research article published in professional peer-reviewed science journal based of above summer research program?

Duke- Reach
Northwestern- Low Reach
GTown- Low Reach
UNC- Match

I think you should get into 1-3 schools on the list but you should add a safety just in case.
