Start with the Ultimate Crash Course

The STAFFS Prep Ultimate Crash Course built into the app, with Christian teaching alongside live instructor chat

This is the highly reviewed course that used to be our standalone $175 program, now baked into the app at no additional cost. Students learn the rules, strategy, and pacing first—because practice works better when they understand the game.

Practice what matters next

Most apps practice whatever you missed. STAFFS ranks weaknesses by frequency and ease, then continually adapts your plan around the fastest path to more points. See how Frequency + Ease works.

Get help at the right moment

No other test prep app builds live tutoring into the plan. STAFFS spots when you need help and gives your tutor the data to plan highly-focused sessions.

Not another question bank

One system coordinates everything.

STAFFS connects strategy, adaptive practice, full-length tests, and live tutoring—so your student always knows what to do next.

Learn the test before practice begins.

Every plan starts with a complete course on strategy. Learn the patterns, shortcuts, pacing decisions, and logic that make every later assignment more effective.

Your day-to-day prep plan

The app turns your date and goals into the right study sequence. It follows your progress, adjusts as you improve, and figures out when a full-length practice test will be most useful.

1:1 help when it matters

Add the amount of expert help that fits your student. Tutors can review the work, answer hard questions, correct bad habits, and target the weaknesses that remain.

A realistic timeline

How long does this usually take?

We’ve seen students sign up for STAFFS Prep just one week before their exam and improve by 60 points. We don’t recommend cutting it that close. Give yourself 4–6 weeks before test day, and you should have enough time to learn the strategy, practice it, and improve.

Flexible access

The complete app at every duration.

Every plan includes the same complete roadmap: targeted questions, full-length tests at the right time, and clear next steps. Choose the study window that fits your test date; add 1:1 help later only if the app shows it would help.

How the app decides what comes next

We don't just find weaknesses. We rank them.

Layer 1

Your areas of weakness

Trigonometry Exponential growth Triangles System of equations Bullet point analysis Vocab Grammar rules

We start by quickly finding the exact areas costing you points.

Layer 2

Frequency layer

Grammar rules Exponential growth System of equations Vocab Bullet point analysis Triangles Trigonometry

Then we order your weak areas by how often they actually show up on the test. This is all based on our analysis of past test data.

Layer 3

Ease layer

Grammar rules Exponential growth System of equations Vocab Bullet point analysis Triangles Trigonometry

Finally, we take the frequency list and make adjustments based on ease. This is where 17+ years of experience really makes a difference, because we know when a topic requires deeper content knowledge and when it can be simplified with tricks/strategies.

Your highest-impact study list

  1. System of equations
