chances of getting into columbia

<p>I am in 10th grade in England and currently doing my gcse’s. I am getting a/a* in my gcse’s. I am part of the student council, prefect team, debate club, and founder of volleyball club. I am doing 2 hours volunteering at a charity shop, reporting for my school and was shortlisted to be part of the most outstanding pupil in journalisms awards. In my old school I was part of two basketball teams, volleyball, swimming, cross country, track and field and did drama aswell was a student ambassador. I also play the piano and flute. I speak fluently in three languages. And currently won a gold certificate in my school for credits. I was just wondering what I can do to improve my chances into getting into Columbia?</p>
