HYP/Penn/Duke

<p>Hello,
I'm a upcoming junior. These are the stats I expect to have by senior year:
4.5ish weighted GPA
3.91 unweighted, 1 b freshman and 2 bs sophomore
2.3k+ SAT
7 AP 5s (although I've heard this doesn't matter in admissions?)
1 4 on APUS</p>

<p>My school is ranked top 20 by some reports. It is a public magnet school.</p>

<p>ECs:
Paid summer internship at a Fortune 100 chemical company
One month volunteering at an orphanage for disabled kids in Shanghai and teaching dance
Teaching Chinese kids w/ disabled parents English
^Soph. summer
Debate 4 years -> probably getting a state level award this year
3 years modern dance club teaching students and inner city kids
UPenn summer leadership program
Started my own website with 2.2k members and 10000 unique visitors monthly.. maybe not worth mentioning</p>

<p>What are my chances at HYP/UPenn SEAS/Duke? I think my teacher recs would be above average and my essays very good. Also, what can I do to improve these two years? I feel that my junior year is competitive and my summers are as well, but I had a weak freshman/soph year with few ECs and slightly-above average GPA.</p>

<p>Also, can anyone give insight on to how ECs are reported on the common app/school apps? I can’t imagine one line being enough to talk about any of my ECs.</p>
