I could not find any information on composite+essay percentiles
I’ve never seen a chart with that info. It’s rare though. Here a tip: colleges won’t care too much about a 12 on the essay. They mostly want to see that you are a competent writer. Not getting a 12 will not be a deal breaker for a single college in the country.
MODERATOR’S NTOE:
Outside of the ACT people, nobody knows. Since the question is unanswerable, I’m closing thread.
