What are my chances at Harvard, Yale, and Northwestern?

I am an international student from South Korea, currently attending an international school in South Korea.
I have 1570 on New SAT, 800 for Math 2, 800 for World History, and 800 for Literature.
Our school is an IB school, so I have gotten into a full IB-Diploma Program.
I have taken: English A HL, History HL, Korean A HL, Theatre HL, Chemistry SL, and Mathematics SL.
I was awarded the valedictorian award, On the IB exams, I have gotten all 7’s except for English, which I got a 6.

Extracurriculars:
I have served as a member of Student Council for 3 years — Vice in my junior year, and President in my senior year for the Student Council Chair(meaning for the whole high school, not just a grade).

I have founded the Korean Association for Children with Leukemia and Cancer(KACLC) Club, in collaboration with the association and have made around 15 wishes of children with severe illnesses as a club(examples of wishes were getting a macbook, meeting a K-pop star, going to an amusement park, etcetera. All money collected through fundraising)

I have participated in various drama productions, including musicals which I have always gotten lead roles, and I was nearly scouted by an actors agency with my performance. I am also a part of a professional theatre group outside of school, which is a group of young aspiring actors and actresses. I have performed in various film and theatre competitions around Korea, awarded the “best male performance in a leading role” award.

I have a great interest in writing. I have been in a publication class of my school since freshmen year, becoming the editor-in-chief in my junior year. I have also written in a magazine called Teen 10 Magazine(magazine for English speaking teenagers in Korea), and served as a Editor-in-chief since my sophomore year.
With my interest in helping ill children, I volunteered for Samsung Seoul Hospital(biggest hospital in Korea) for 3 years. And inspired by a few children I’ve met during this experience, for my personal project, I have written a 200 page novel, which was published in Korea. It sold quite a few copies, and I have donated all profits to the KACLC Association.
With the publication of the novel, I was awarded “Korea’s future leader of arts” award by the Culture Minister of Korea.

I also was awarded in total of 5000 dollars in the writing competitions I have participated in.

I have been in JV basketball team in my freshman year, and Varsity since sophomore year, and have become the captain in my senior year. Named MVP of the entire league in my senior year.

I have worked with Save the Children Korea for all 4 years in my high school, volunteering there during every school breaks. I was a translator – translating letters from the sponsored children into the Korean sponsors(English to Korean).

Plus, I have hosted a podcast for teenagers, getting the most number of downloads out of all teenage podcasts.

Lastly, since my sophomore year, I have worked as a staff member in professional musical and play sets, and also worked as a tour guide for foreigners staying in this youth hostel, travelling with them all around Seoul.

I have written my essay, and received recommendation letters from my counselor, newspaper teacher, and English teacher.

I would like to pursue writing and acting in my undergraduate years. I have once gotten a B in English during my freshmen year. Will that drag me down?

How are my chances?

It’s hard to guarantee anything because you’re an international. However, you are definitely qualified for these schools.

yes, your chances are very good

@JerseyKid321 What does “very good” mean when the average admit rate is 8%? Is that 10% or 12%.

The OP does have great stats – but being an international, faces the steepest hurdles. OP should get some nice acceptances – from schools like H, Y and NU – chances are less than average.
