@Blueberryyyyyy Yale has a RD admit rate of under 4.5%. Harvard’s is even lower. International applicants are generally believed to have an admit rate about 1/3rd that of the overall applicant pool.
Before you even figure in your stats, your odds are under 1.5%
25th percentile ACT at Yale and Harvard is a 33
Only 4.27% had an ACT in the 24-29 range at Harvard (Yale doesn’t break the numbers down.
25ACT math section score is not at all helpful for a potential econ major at Y or H where econ requires strong math/CS skills.
The odds for any international applicant in the RD round are slim. Add standardized test scores below the 5th percentile and the odds become pretty bleak.
Substantially higher standardized test scores certainly wouldn’t hurt, but even with a 36, the odds are still against you.
Generally speaking ECs help the admissions committee distinguish between an excess of students with outstanding stats and can not outweigh less than stellar stats.
