Extra rec letters

By the way, on the common app there was room for up to 4 teacher rec letters, and since I had a total of 4 on the common app (from applying to different schools with different rec letters), I submitted all of them. In that case, do they read all the 4 letters? Does the order of adding recommender matter? Bc the last 2 showed up as “additional” when I submitted them.
Not that it would change anything otherwise at this point, but I just want to know. (I hope they read them equally, I added recommenders in automatic order that common app made…)

They take into consideration everything you submit to them, so yes, all of your rec letters were read. I doubt they would’ve been given different weights considering the fact they very likely are aware they go in alphabetically.
