HI, I’m a high school student and my dream school is to go to UND. If you went/go to UND, can you please tell me your GPA & ECs during your high school years? I’m not going to copy you, I just want to compare mine to see if there is a chance for me. 
thank you!
This would be more useful than looking at any one individual’s statistics. Also check Naviance for your HS if that is available.

Look at the results threads for the past years to get an idea of what students are getting accepted.
Refer to the above recommended website but in a nutshell, Notre Dame is looking for the to 1 to 2 percentile in standardized tests nationwide or the top few percent of your graduating class or both. I’m sure some legacy or athletes are admitted that aren’t this high but despite this the average test scores / class rank of admitted freshman are wicked high
