Grades its own evidence
Every claim tracks back to an extracted excerpt, slide, or recorded syllabus entry.
Android · Adaptive Engine
Study the exam, not just the subject.
ExamDNA analyzes your course materials, builds an evidence-graded model of your exam, generates independently verified practice, and sharpens itself from what actually appeared on test day.

Why ExamDNA is different
States confidence and limits
Clear bounds on what is known vs. guessed. Confidence is capped when files are thin.
Verifies questions independently
A separate verification pass screens answer keys and syllabus alignment before you see an item.
Learns from the real exam
Log what actually appeared after exam day. Hits and misses feed the next Exam DNA cycle.
Methodology
From your material to a verified exam
A five-stage loop: course material → Exam DNA → evidence-aware practice → feedback from the real sitting.
01
Add your material
Notes, slides, PDFs, photos of handwriting, the syllabus, previous exams. Original files stay on your device.
Local-first parsing
02
Build your Exam DNA
Weighs available evidence, hypothesizes a blueprint with stated confidence, and lists blindspots.
Confidence bounds
03
Generate practice
Exam Builder starts from your blueprint. Each question is checked by an independent verifier before you see it.
Verified generation
04
Measure honestly
Exact scores where deterministic, estimated ranges where rubric-based — including where you were sure but wrong.
No vanity scores
05
Replay the real exam
Record what actually appeared. Hits, misses and surprises feed the next calibrated Exam DNA.
Loop closure
Predictive Diagnostic
Exam DNA: a prediction that shows its evidence
ExamDNA builds an explicit contract between your source materials and what the available evidence supports about the test — including when that evidence is too thin to pretend certainty.

Topic DistributionExample mix
When evidence is thin, ExamDNA says so. Confidence is capped and limitations are stated — so you know how much to trust a pattern before you study to it.
Verified Execution
Practice against the exam, not random questions
Exam DNA → Exam Builder → practice sitting → verification → results. The screens below are from the real Android app, using demo course content.

The prediction meets the real exam
- Before. ExamDNA makes evidence-supported preparation assumptions from the materials you added.
- Real exam. After exam day you record what actually appeared.
- Next cycle. Hits, misses, and surprises become evidence for the next Exam DNA run — within bounds, not a made-up accuracy score.

Operational Principles
- Prioritises topics by predicted weight × your measured gap × time pressure.
- Enforces structured rest breaks and a hard daily fatigue cap.
- Includes skip-for-now routing so you do not stall on one topic.
