Chances of acceptance into Exeter, Andover, and St. Paul?

Quite curious since I am applying for freshman of 2018. There’s small achievements here and there but I am going to cover the major aspects of my application. And do the three schools look for particular students (ex. STEM, volunteering, etc.)?

Academics -

  1. As of now, I attend Stanford Online High School, one of the top private schools in the nation. My strongest areas are science and math where I qualified (passed placement exam) for AP Chemistry and H Precalculus as an eighth grader. My writing skills are exceptional however I have not received any huge recognition or award.
  2. Offered full scholarship to attend OHS (see Possible Hooks).
  3. Earned award for highest SAT score for writing and mathematics in my district.
  4. Qualified for gifted program and took/passed chemistry and biology honors there.
  5. Middle Level SSAT percentiles: 99% for quantitative (perfect), 90% for verbal, 87% for reading, and 97% overall. Keep in mind this is a middle level taken a year ago, though I'm not sure if it will be substantially difficult compared to high level.

Outside -

  1. Run an academic website/blog offering my opinion on recent news, novels I have read, and (most substantially) chemistry notes. The design is pretty well made but (since transformed site into different concept recently) relatively empty besides the chemistry section [which I hope to accentuate]. Here's the site:

Still in the midst of editing but will definitely have it stable within a week’s time.

  1. Played tennis competitively until I suffered from an injury. Recovered and fell to a three star during my absence. The coach might pull some strings depending on the players next year.

Possible Hooks -

  1. Both of my parents are born out of the country and struggle financially. Entered into Stanford OHS by earning a full (selective) scholarship covering entire tuition which I am extremely grateful for.

Considering the online platform it is, I have no clue as to what my instructors perceive me as. As of now, my grades are all A’s but I am struggling a bit. Not sure as to the effect straight A’s will play in the top percent of applicants. Currently looking for research opportunities but I don’t think they take me seriously being the age I am.

Thank you for your help!
