Is Hopkins a school that takes a ACT superscore? Do they care how many times you take it??
The JHU web site says they superscore ACT and SAT, and when the baseball coaches asked for my son's scores, they specified that he should send scores from all the ACTs he took (two, in his case). So far as I know, every school allows you to take the tests as many times as you want, and to only submit the score(s) you choose. (I assume JHU wanted all of my son's tests so they could verify what the superscore would be.)
When my son met with Coach Babb earlier this summer, he was told that they like to see at least a 33 for their baseball recruits. They said they can make lower scores work sometimes, but a 33+ is good.
Based on the data I have seen, a 33 is 98th percentile, while 34-36 are gradations of the 99th. I'm really glad I applied to college over 30 years ago.
