GRE Quant
A score is treated as an output. The diagnostic looks underneath it.
- Baseline performance
- Error composition
- Timing
- Accuracy
- Transfer
Measurement
Progress should change what the learner can do.
Pristone measures the capabilities underneath a score, finished project, or interview result. The evidence is selected before the intervention and revisited after meaningful work has occurred.

The Pristone Method
One capability loop across every track.
- Diagnose
- Prioritize
- Build
- Test transfer
- Measure
- Re-prioritize
Progress at Pristone means an observable improvement in performance, independence, judgment, or transfer relative to a stated baseline. External outcomes may matter, but they are never treated as fully controllable or guaranteed.

Domain scorecards
The dimensions change with the work
A single universal score would hide the differences between exam performance, research quality, software engineering, and open-ended design.
AMC 10 and AIME
Readiness includes what the student knows and how the student makes contest decisions.
- Topic depth
- Recognition
- Problem selection
- Pacing
- Verification
Coding and software engineering
Progress means increasing ownership of the work, not merely finishing more exercises.
- Independence
- Debugging
- Architecture
- Complexity judgment
- Completion
Machine learning and research
A working model is not enough; the evidence and experimental process must hold up.
- Question quality
- Baseline
- Leakage safety
- Evaluation
- Limitations
System design
The assessment follows the reasoning path from scope through failure behavior and communication.
- Requirements
- Estimation
- Data model
- Architecture
- Tradeoffs
- Communication
Evidence cycle
How progress is checked
Record the baseline
Capture what the learner can currently do, the conditions of the attempt, and where support was required.
Name the target behavior
Define what should become more accurate, independent, timely, defensible, or transferable.
Collect work evidence
Use problem attempts, code, designs, explanations, project artifacts, or timed performance as appropriate.
Retest under changed conditions
Use a new problem or reduced scaffolding so improvement is not confused with repetition.
Update the priority plan
Keep, change, or retire the intervention based on the new evidence.
Reporting
What a useful progress summary should contain
Observed evidence
What the learner attempted and what was visible in the work.
Interpretation
Which constraint the evidence most strongly supports, including uncertainty where it remains.
Change since baseline
What improved, remained unstable, or could not yet be evaluated.
Next priority
The smallest set of actions likely to create the next meaningful change.
Measurement supports better instructional decisions. It does not guarantee a future score, admission, publication, promotion, or job outcome.
Continue through the Pristone system
Establish a useful baseline.
Begin with a paid working diagnostic and leave with a written account of the current evidence, the first priority, and how progress can be checked.
