Here's what St. John's actually looks for, pulled from the real admitted-student numbers — not a wish list. Use these as the bar to clear, then see where your own profile lands.
You'll want to be at or above the 3.4–3.85 band. A few B's are survivable if the rest of the application is strong.
Most admitted students score in the 1080–1280 SAT / 21–28 ACT range. Many selective schools are test-optional right now — check St. John's's current policy, but a score inside this band only helps.
Hitting these numbers gets you into the pile. It doesn't get you in. St. John's accepts 74.0% of applicants, which means most students with the "right" GPA and scores still get turned down. Course rigor, essays, recommendations, and a clear spike are what separate admits from the rest of the qualified pool.
