Found: School where kids are ranked!

Hello! I read this book about 2-3 years ago and I vaguely remember that the cover may have had orange I found it in my middle school library it was a fiction and had elements of mystery. It was about a girl(main character) who went to a school where they had smart watches displaying a rank out of 100 if you where late to class or where talking during class teachers had the ability to dock you points at the end of high school what collage and how well you get treated depended on your number(lower the number lower treated in society and not good collage higher number and it was the opposite) she finds out about a secret society of people who are trying to change this the society must remain a secret and not many people get to know about it. That's about all I remember I really want to read it again but cant remember :( I hope this is enough info for someone to find out!
