I’m a senior and took the ACT without the essay and got a 32. However, I took the test again with the essay and went down to a 30. Some colleges need you to submit the essay so is there a way to submit both scores?
You can send both, but some schools will only consider the one with the writing, some might consider all scores, this will be explained on the colleges' websites.
It depends on the school. Some want the writing in the same sitting.
