Here's what Saint Mary's College of California 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.
The admitted middle 50% lands at 3.25–3.7, so this is reachable with solid grades and a coherent application.
Most admitted students score in the 1140–1310 SAT / 24–30 ACT range. Many selective schools are test-optional right now — check Saint Mary's College of California'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. Saint Mary's College of California accepts 86.0% 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.
