Importance of Class Size

In our nation’s system, high school ends at grade 10 (then you go to college). So after graduating grade 10 (as 1st out of 135), I moved to an international school with grades 11 and 12. My concern is that now, I am 1st out of 25. Basically, my percentile rank shifted from top 1% to top 5%.
I heard class rank (in relation to class size) is an important factor, so is there any way I can report this? Perhaps in an Additional Details corner? Or will reporting this make me sound too self-promoting?

Assuming you’ll be using the Common App for some of the schools you’re applying to, your counselor (assuming you have one) would send a school report that would state your ranking on it of 1st out of 25. Also, you can report class size inside your Common App as well.

Once again, that’s assuming you’re using the Common App. If otherwise, I have no clue!

Thank you for the reply, but my problem was that my current guidance counselor would be reporting my current stats (1st out of 25). But seeing as that top 5% isn’t really competitive for the schools I am applying to, I was wondering if I should report my ranking in my previous school (1st out of 136) which would make me top 1%.

I think you’re being a tad unreasonable here. They’re not looking strictly at numbers, they’re looking at how you perform in the context of your class. If you reported your ranking of 1st out of 136, the information you would be submitting wouldn’t match up with the information in the official, verifiable information in the school report, and you’d just end up with a discrepancy that wouldn’t serve you at all in admissions.

Edit: Also, perhaps I’m speaking out of my depth, but I would believe that top 5% would still be competitive enough, no? But, since you’re an international student (at least that’s what I’m guessing based on your nation’s schools and everything), I don’t exactly know if that suddenly makes you noncompetitive or not.

This sounds like what I have heard for India or Pakistan

You’re overthinking this. It doesn’t matter. You’re ranked number 1. The fact that that is top 5% is irrelevant.
