Others gave you good general advice, so I was give you a really specific comment.
I think people have to be careful about what counts as a “good” test score in a test optional world.
I’ll just use Princeton as an example.
The enrolled class described in their 2020-21 Common Data Set (with 71% submitting an SAT score, and 45% submitting an ACT score), had a 25th percentile of 1460, and 75th percentile of 1560. These are enrolled students, so prima facie all these people succeeded. The complication is hooked applicants are evaluated differently. And also when people are required to submit scores, people can get admitted despite not-so-good scores. Still, in such a pool, 1540 was closer to 75th than 25th, and so I am confident that was a helpful score in that class.
Their next Common Data Set, it was down to 56% submitting SAT, 35% ACT (so we are now in test optional world, although apparently most of these kids submitted). 25th moved up to 1470, 75th stayed 1560. Not too much of a difference, but it is consistent with a small percentage of eventual enrollees with lower scores not submitting, either because they couldn’t or because they thought it would not have been helpful.
OK, then the latest Common Data Set: 60% SAT, 25% ACT, even more opting out. 25th percentile jumps to 1510, 75th percentile goes up slightly to 1570, and now they report 1540 as 50th.
Oh no, it is getting harder to get a good score for Princeton, right?
For the most part, probably not. Because if more people with lower scores opt out, the 25th mark will naturally move up, potentially quite a bit. The 75th might creep up a little (although one would expect less than the 25th), and then the 50th might move up in between. Which is consistent with what is happening at Princeton.
But you are also removing from the pool people who before had to report scores, but got in despite lower scores. Meaning a deeper percentage of the people who reported scores and enrolled actually had helpful scores, not unhelpful scores they managed to outweigh.
Hopefully that logic is clear. The bottom line to me is if you are around the 50th mark for enrolled students who chose to submit a test score in a test optional world, that is almost surely a helpful test score. Probably a good bit below the 50th too. I think only down close to the 25th, say, might you be running into a lot of people in the remaining pool of concern, namely hooked admits for whom that was a helpful score when it wouldn’t be so helpful for unhooked admits.
So that’s my two cents. Your 1540 very likely remains a helpful score at these sorts of colleges. And you need a million other things too. But I think you should at least feel like this is at least one helpful factor.
