ranks are stupid imo.
50 people could get a 100% score. They all be the same, but someone has to get the 50th rank still despite doing just as good as 1st place.
on the other hand, out of 50 people, everyone bombs the rankings and 1st place possess a 1% score.
No not really...we're talking about exams like finals or midterms which are usually graded on the scale of 0 to 100. While it is theoretically possible for 50 students from a class of 200 students to get the highest possible score, it's extremely unlikely for even 10 kids to get that highest possible score...from my experience, while it is possible that a majority of people can get over 90, but not all of them get the same score...let's say 2 get 100, then another 2 get 99, then 3 kids get 97, then 1 kid get 96, and so on...as you go more up the classes, it flanks out even more (in my high school, over 80% kids would get at least a b in their exam, but in college that b was the average...at least that's what I experienced)
So that establishes a clear rank among the students In a single subject...now you have all the subjects and combine those scores and Now you will have more diversities...kids who excels in all subjects will be placed higher than the kids who excels in some of the subjects who will be placed higher than kids who only excel at one subject who will be placed higher than kids who didn't get any good score in any of his subjects
As for diversities, this is what I mean...imagine there's a six subjects...one student scores 100 on each of them and then another student scores 100 on only 5 of them and get a 99 on the 6th subject...now even tho they both excels in all subjects, because the 2nd kid got one less point in one of the subject, he will be ranked 2nd...notice how both of them would have shared the 1st rank in 5 of the subjects
now you may ask OK then how would you rank kids who got the same score? In those outside factors may come in like what's his overall performance in class or what extracurricular activities they do...for example a kid who did his homework or class assignments better than the other kid he will be ranked higher or a kid who participated in more extracurricular activities will be given a higher rank
Or they could just have both kids share the same rank (for example my high school had multiple valedictorian, and valedictorian is supposed to be the #1, meaning multiple people shared the same rank)
Sorry for long ass boring probably not right comment but I wanted to give a perspective as to why I disagree with your statement
Tldr: while it is theoretically possible for 50 kids to get a 100, realistically not even 10 kids get a same score much less getting a 100
