Top priorities from the principal examiner before you revise
TPAT1 Medical Aptitude is the medical-school aptitude paper used in TCAS. The official structure is three parts, 300 marks total, completed in 180 minutes, with aptitude, ethical reasoning, and medical-readiness skills assessed through high-stakes selection items.
Official blueprint: three parts, 300 marks total, 180 minutes.
TPAT1 uses the TGAT/TPAT score conversion: Ti = 50 + 8.69031 * (raw - mean) / SD.
The paper is designed for selection into medical and health-science pathways, so professional judgement is assessed alongside reasoning accuracy.

Deep insights
What top candidates did
Techniques and approaches examiners rewarded in this series
1. Pace by marks, not by comfort
With 300 marks in 180 minutes, budget roughly 60 minutes per 100-mark part. If one section feels familiar, still leave enough time for the remaining parts.
2. Use a four-principle ethics check
Test options against autonomy, beneficence, non-maleficence, and justice. A choice that violates confidentiality, safety, or fairness is rarely best.
3. Stay inside the stimulus
Medical aptitude items often provide all necessary facts. Do not import specialist medical knowledge unless the item explicitly asks for general science.
4. Annotate data before calculating
For tables, graphs, and short research summaries, mark variable, unit, comparison group, and conclusion before doing arithmetic.
5. Practise long concentration blocks
The paper is three hours. Build stamina with full-length mixed practice rather than short isolated ethics drills only.
6. Choose professional communication
In situational items, prefer clear explanation, consent, respect, referral, and escalation through proper channels.
