I’m applying to a bunch of schools and was looking at the rec letter requirements. Do I need two different letters for each school I apply to? If not, then how to I send it to multiple schools through the common app/other methods?
Nope! Just talk to your guidance counselor to see how they send the letters at your school. You can reuse your recommendations for all your applications.
I’m not sure how it works in your school, but here’s what happens in mine:
Every single senior gets 3 letters: two from teachers and one from his/her college placement advisor.
We upload the letters onto Naviance.
From there, College Placement ensures that the whole file goes along with the application.
No, just send the same letters to all colleges. That’s what I - and everybody else, I’m assuming - did! Good luck with your applications 
Thank you all!
