I didn’t know that was something I was supposed to do until I submitted my application to two colleges. The order is totally different than what my order would actually be, and the thing that matters least to me is ranked at the top. Is the order something that the colleges really look at or is the important thing just that the activities are there? Should I be concerned?
It’s not a huge mistake as I think at least one of my friends has made that same mistake. However, it does speak somewhat on behalf of your slight negligence as I believe it does say somewhere on the sidebar to rank your activities.
Admissions will be able to see that your time commitment and anything you wrote in your essays and just from the hours and descriptions, deduce that you made that mistake. It’s no big deal. Correct it for your other colleges and move on with life. It won’t be the reason that you’re rejected in my opinion.
