A wrong high school code can send the score report to the wrong counselor inbox. Fix it in MyACT as soon as you see it. The Composite does not change.
How to fix it
Update the school in MyACT, then ask ACT to correct a report that already posted if the counselor never received it. How to contact ACT.
If a college send used the wrong school
The college still gets the score. The high school copy is what broke. Sending: send scores to colleges.
The bottom line
Match the code to the school on your transcript. Fix it before scores post if you can.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
