Hi there,
I have a friend in my grade who’s applying to 4 of the colleges that I’m applying to this fall (Pomona, WUSTL, Brown, Duke), and I don’t know how I should feel about this. The thing is, she has much better grades than I do and a couple of more awards than me, while I have slightly better extracurriculars and more activities (but I still do have decent grades) than she does. If you were in my place, how would you feel?
Reserve judgment until you get decisions. You may both get rejected (or both accepted!) and then you would have wasted all that time resenting her.
Besides. Check out the results threads on here. There are much, much bigger fish to fry!
You are feeling competitive which is normal.
You can’t assume that she will get into the schools you plan on applying to and that you won’t.
Continue with your studies; do your activities and write your essays. You don’t have time to be worrying about your classmate’s actions.
It wouldn’t matter because I’d be applying for the most competitive major and actually planning to go to my safety instead.
So then again, I spout who cares if you got in and I didn’t 
Also, later on for jobs, a person can have better/worse grades but the interview is most important
Presumably, a lot of applicants are more competitive than you. Why does it matter if they come from your school or not? Will they only accept one person from each school?
Thanks all, I think I was just frantically worried about it for just a few minutes that I couldn’t control myself
If you both get accepted, you have some carpool possibilities for breaks.
Put it out of your mind. You can’t control what other people do. There is nothing wrong with a bunch of people from the same high school applying to the same college. Be generous - if she gets in and you don’t, try to be happy for her. Wherever you get accepted and decide to go, be happy for yourself too! 
I’d apply to additional similar schools. Many schools only accept one student from a typical high school.
WUTSL, Duke, and Brown are ridiculously competitive low acceptance rate schools for all but the absolute best students.
Lots of good ideas here on options.
I think I’d also feel a little worried. But, I think you’ll be okay! You could both get in! Be confident.
I don’t think it’s good for a bunch of people from the same HS to apply for the same school, though. I feel like EVERYONE in my county applies to the county college, or two others!
I am also worried about this. In my small class of about 112 the few of us at the top are all planning on applying to top universities, but one girl has 2 perfect test scores and an overall great app, another is a state champ in track and xc, another’s dad died when she was a baby - which is about the only hook you can come up with going to a tiny Wi school where you can count the minority students on one hand and no one’s parents are legacies because they all went to tech school for ag-mechanics or something.
