Questions about class size and class rank

<p>Hi there, I am an international student, and little bit confusing about this parts( size and rank) in application process( honestly, not only in application).
So, my question was, what does it mean class size in terms of US school? Its definitely sounds very strange, but let me explain: for example, we had around 32-33 students in our class, but I saw a lot of articles with class size 200-300 or even more! So, I need to write amount of people from all graduation classes?
My second question about class rank, mostly about decile and quartile and etc ranges. How to calculate? I mean,in our school we had 6 graduating classes, and from all of them 5 valedictorians. It that way, how to calculate class rank? We've had some kind of it in my class, I was first in my class, so need to put 1%? However, I need to use only my class rank or rank in terms of all graduating classes? ( All information need for my school counselor)</p>

<p>Thanks a lot !!!</p>

<p>In US schools, the high school is generally divided into grades by age, often 9th (freshman), 10th (sophomore), 11th (junior), and 12th (senior). When someone says they are 5th in a class size of 300, they mean within all the students of their grade level, which this year will be titled “The Class of 2014.” What is confusing is that within those grades, different courses are administered (English, Mathematics, Art, History, etc.) and those courses are also called “classes,” as in “I’m late for my chemistry class.” But rankings are based on the entire grade level.</p>

<p>I don’t understand your situation though. What do you mean by 6 graduating classes, with 5 valedictorians?</p>

Wow, thanks a lot for quick answer! Well, I mean about classes mostly, 6 senior classes with 32-33 students each, and 5 valedictions from all of them(classes). So, after your comment, I understand, that I need to find my class rank from all graduation class 2014, which means my rank from 195+ people?</p>

<p>Yep! You would be correct with your second response. It’s not really self-reported, though, so you’ll just have to make sure your Guidance Counselor (or your school’s equivalent) knows.</p>
