I’m trying to figure out colleges tend to receive AP scores simultaneously or earlier than the student?
It may be a couple of days earlier depending on your state. Students’ access is staggered based upon the state of residence, but I believe colleges (and high schools) receive the scores on the first available date. In the past, students who have graduated HS have been able to access their scores in advance if the college’s registrar has posted them to the student’s account.
Thanks! My daughter is waiting on the results in order to register for the next math class.
Some colleges allow registration pending the results, so she might want to research that.
We just came home from registration this week. They allow engineering students to go ahead and register based on a students predicted score, but forbid business students to do the same.
Oh well, I tried. 
Regardless, good luck to her.
