THE METHOD · A STUDY IN THREE MOVEMENTS
Measure. Then
move.
Satclub's method was built by former College Board item writers and 99th-percentile tutors. It pairs a precise diagnostic with a four-week adaptive plan — and reassesses until you hit your number.
The Movements
Three movements, repeated.
The Diagnostic
A 90-minute adaptive test that measures your current score within ±20 points and identifies the six units that will move it fastest.
The diagnostic adapts to your answers in real time — harder questions when you're hot, easier when you're cold — so we can pin your ability with far fewer items than a full SAT.
It's calibrated on 140,000 historical scores and scored on the same 400–1600 scale as College Board. You get back a score, six personalized focus units, and a target-score probability curve.

The Four-Week Plan
A daily plan, authored by humans, adapted by software. 45 minutes a day. Drills, lessons, reviews — in the order that moves your score fastest.
Every lesson is written by a former College Board item writer or 99th-percentile tutor. The order is set by a spaced-repetition engine tuned to the Digital SAT's item types and timing windows.
We don't sell 'unlimited practice.' We sell the right questions, in the right order, at the right time. Most students finish in about 21 hours of work across four weeks.

The Reassessment
Every five weeks, we reassess. The plan recalibrates against your weakest remaining units and updates your target-score probability.
Progress is not linear. Students often plateau at week three. The reassessment catches the plateau, identifies what's still stuck, and rewrites the next plan around it.
Most students cycle through two or three reassessments before test day. The cost of each is zero — it's included in every Member plan.

The Research
Measurement, not
motivation.
Satclub's engine is built on Item Response Theory — the same psychometric framework College Board uses to score the actual SAT. We don't guess what to teach. We measure, then teach the measurement.
