What our students actually gain

Average gains, ending percentiles, and how they compare to published research — from a multi-year analysis of students who completed our program. Our own data, not someone else’s study.

The typical journey

Our average ACT student starts at a 22 — the 69th percentile — and finishes at a 28, the 90th percentile. On the SAT, a typical start of 1210 ends at 1400, clearing the 1350 line that separates “below elite” from the top 10%.

That’s the typical journey, not the ceiling. Every year we also help students earn perfect and near-perfect scores on the SAT and ACT.

How that compares to typical test prep

Published research puts the typical retest-with-preparation gain at about +1.4 ACT points (Schiel & Valiga, 2014) and roughly +30 SAT points (Briggs, 2009). Our students average about 4× that.

Every figure above comes from our own student records, kept current through the most recent completed cohort. Averages describe students who completed the program; individual results vary with starting point and practice.
