Chancing for Purdue INTEL ISEF

Hello. I am chinese. I got a 1590 on the SAT, and a 800 on the Mathematics 2, and a 760 on Chemistry subject test. I am a three time Intel International Science and Engineering Fair Finalist, and have won 2nd in my last year. I am a top 400 USABO qualifier. I have played violin for the last four years, and have played at Carnegie Hall. I have pretty decent grades top 10%, i am not reporting ap test scores. I also have over 5 leadership positions in my school. I am applying to Purdue CS. What are my chances, and do you think I will get merit scholarships.

I think you have a high chance of acceptance but less than 15% of students receive merit scholarships and most of them go to instate residents.
