How should a student even start?
What is the best way to understand the test’s strategy, rules, and pacing before drilling questions?
Why the system works
17+ years of test prep.
17+ years of test prep.
Finally organized into one clear system.
Families have more test prep options than ever—and less clarity about what a student actually needs. After 17+ years of teaching, we built one system that lines up strategy, practice, full-length tests, and optional tutoring—and finally gives families a clear path forward.

Before studying even starts
Parents are being asked to build the system.
1:1 tutoringCoursesPrep appsBooksYouTubeCollege BoardKhan Academy
Does my student need an app—or a tutor?
Should we start with a course, a book, or a practice test?
How much help is enough without overpaying?
Who decides what they should work on this week?
How do I know whether any of it is actually working?
The hard part isn’t finding prep. It’s knowing what to use, when to use it, and how to make all the pieces work together.
The coordination problem
Parents are left to turn a mountain of prep options into a working plan.
The stress isn’t only about finding resources. It’s deciding what comes first, what comes next, and when the plan needs to change.

The research behind the system
We treated test prep like an optimization problem.
“How do we use a student’s limited time to create the largest realistic score gain?”
We looked at how often each skill shows up, how quickly students usually improve it, and what their results say they should do next.
The Practice Software now makes those decisions for the student, so families get a clear next step instead of another pile of resources to manage.
The decision engine
Every assignment has to earn its place.
Finding a weakness is easy. Deciding which weakness is worth fixing next is the real work.
Layer 1
Your weak areas
TrigonometryExponential growthTrianglesSystems of equationsBullet point analysisVocabularyGrammar rules
The software identifies the individual skills holding the score back.
Layer 2
Frequency
Grammar rulesExponential growthSystems of equationsVocabularyBullet point analysisTrianglesTrigonometry
Skills that show up more often move higher on the list.
Layer 3
Ease
Grammar rulesExponential growthSystems of equationsVocabularyBullet point analysisTrianglesTrigonometry
Then we move the quickest, most learnable gains toward the top.
Result
The highest-impact next step
- Systems of equations
- Grammar rules
- Bullet point analysis
- Exponential growth
- Triangles
- Trigonometry
- Vocabulary
The software gives students the work most likely to move their score—not just the next page in a book.
The result
One coordinated roadmap for every stage of prep.
Each part works on its own. Combine them for the full system, and add tutoring only when you need it.
