Can the essay score be sent separately.
If the school superscores should all 3 be sent?
For schools that require all scores, of course you would have to send all three.
For schools that take highest sitting, I would send either October or June… depends on how much you/they value the composite vs the essay.
For superscores, you should probably just send March and June.
Keep in mind, though, that the College Board does NOT charge any differently for how many SATs you send to one school in one order; sending 3 would cost just as much as sending 2 and it probably wouldn’t hurt you, so do what you want. Some schools will want to see all test scores, even if they do not REQUIRE all test scores, even if those scores would not be superscored. Just read up on each school’s policy. You can find it on the College Board website or each school’s website, and I would recommend you check both places.
And as far as I know, the essay can not be sent separately. But I also don’t think it is typically weighted in the decisions process as much as the overall score, but it all depends on the school.
