Limited students accepted per SAT cycle.
Private strategy.
Every student follows an individual protocol built around their exact score profile.
Obsidian Intelligence.
A proprietary performance layer that identifies why points are lost—not only where.
Obsidian Intelligence
Not just what you missed. Why you missed it.
Obsidian Intelligence analyses the patterns behind score loss: timing instability, cognitive overload, retrieval weakness, attention drift, decision-making under pressure, and question-level error patterns.
Reading & Writing
Accuracy declines after minute 24.
Maths
Strong knowledge; weak translation under pressure.
Decision pattern
Correct answers changed late in modules.
Early-section execution
Pacing instability in the first half limits access to the highest score range.
The required first step
