We use test data and 17 years of teaching experience to identify the skills with the biggest score potential—and match each part of prep with the right kind of learning.
See how it works ↓We’ve analyzed past tests question by question to understand which skills appear most often. Then we combine that with teaching experience: which skills can students improve most quickly?
That’s Frequency + Ease. Your student’s results help determine which of those opportunities to tackle next.
From the skills you need to work on to the ones with the biggest score potential.
The software identifies the individual skills holding the score back.
Skills that show up more often move higher on the list.
Then we move the quickest, most learnable gains toward the top.
The software gives students the work most likely to move their score—not just the next page in a book.
Understanding a strategy, building a skill, and getting past a sticking point call for different kinds of help.
Learn the rules, shortcuts, and approaches you can apply across SAT or ACT questions, with instruction focused on high-value skills.

A smart question bank prioritizes what to work on using Frequency + Ease and your student’s results, then adjusts as they improve.
Their test date and target score keep the work focused on the time they have.
