What are my chances of getting into an ivy league school?

You have a shot because your GPA seems very high, but you make no mention of whether these cles were accelerated/honors. If they are not honors, you can probably forget about an Ivy League because many students can get straight A's in non-honors cles. You also don't mention too many extra curricular activities other than athletics which is good, but you need more than just one extracurricular activity to even think of an Ivy League looking at your application. The fact that your are an international student should help your chances, though. Did you take the SAT's or international equivalent, because those scores are also determining factors. Of course, be sure to right an excellent essay and see if you can get some letters of recommendation. We truly need more info to see if you have a legitimate shot, but with the info given I would say you have an outside chance, though not likely you would be admitted, I'm sorry to say. Good luck!
