Future work can retune after a plan-launched session
PsychSAT ranks skills from your attempt history, mistakes, confidence, and time since review. After a session launched from the study plan is completed, future unstarted days can be rebuilt around the new evidence.
See how the adaptive loop works →A focused path that adapts live
A focused session starts at medium difficulty. Your first Check moves the next question one step harder after a correct answer or one step easier after a miss, so the path grows from live performance.
Explore live adaptive practice →Psychtopus tutors the question in front of you
The tutor uses the current question, answer choices, your selection, recent attempts, skill history, and conversation context to choose the next useful hint. It scaffolds before revealing.
Meet the Psychtopus tutor →A projection with visible uncertainty
Your trajectory to test day can use completed practice-test scores and an uncertainty band. It is an estimate, never a guarantee. A completed full test gives the model a stronger baseline.
Full-length adaptive tests →Try three right now.
Three independent SAT-style questions, one try each, using the same first-check grading rule as the app. No account needed.
