What the exam actually rewards
SEHS is a concept-based experimental science. Marks come from accurate content, application to unfamiliar data, and justified scientific reasoning—not isolated memorisation.
3
Integrated themes
Exercise physiology and nutrition · biomechanics · sports psychology and motor learning.
76%
External examination
Paper 1 combines multiple-choice and data questions. Paper 2 uses short and extended responses in context.
24%
Scientific investigation
One individual report, maximum 3,200 words, assessed on research design, data analysis, conclusion and evaluation.
| Component | SL | HL | Weight |
|---|---|---|---|
| Paper 1 | 1 h 30 min · 30 MCQ + data questions | 1 h 45 min · 40 MCQ + data questions | 36% |
| Paper 2 | 1 h 30 min · short + extended response | 2 h 30 min · short + extended response | 40% |
| Scientific investigation | 10 hours · 24 marks · 3,200 words | Same criteria and word limit | 24% |
Do not overstudy
If a fact is not needed to explain a syllabus concept, compare systems, interpret data, or justify an applied answer, it is probably not an exam priority.
Syllabus mapA B C
Three themes, 29 topics
Use this as a scope check. A topic is mastered when you can explain the core model and apply it to sport, exercise or health.
Biomechanics
Anatomy, tissues, muscle, levers, motion, fluid forces, movement analysis and injury.
- B.1.1–B.1.4
- B.2.1–B.2.3
- B.3.1–B.3.2
Psychology & motor learning
Personality, toughness, attention, learning, motivation, stress, coping and goals.
- C.1.1–C.1.2
- C.2.1–C.2.2
- C.3.1–C.3.3
- C.4.1–C.4.2
- C.5.1–C.5.2
Interactive chapters
IB SEHS chapters, connected to the Vitalite Textbook
Use each chapter as a focused learning loop: open the visual, watch the linked explanation, then use the Vitalite Textbook chapter to build the underlying foundation.
Chapter 01 · A.1
Communication & homeostasis
Nervous and endocrine coordination, transport, thermoregulation and the systems that keep performance stable.
Chapter 02 · A.2–A.3
Fuelling, energy & training response
Hydration, nutrition, ATP systems, training qualities, health benefits, fatigue and recovery.
Chapter 03 · B.1–B.3
Biomechanics & injury
Anatomy, joints, muscle contraction, levers, forces, fluid mechanics, movement analysis and injury care.
Chapter 04 · C.1–C.5
Psychology & motor learning
Personality, toughness, attention, motivation, arousal, coping, goals and imagery.
Essential revision
All 29 syllabus topics—without the noise
Each card contains only the must-know ideas, the overlearning boundary, one exam move, and one retrieval check.
No topic matches that search.
Internal assessment
The scientific investigation: 24% in four equal criteria
Conclusion and evaluation together carry 50% of the IA. The mark comes from justification, not from a long methods section.
6
Research design
Specific contextual question, relevant data, reproducible method, controlled variables, safety and ethics.
6
Data analysis
Relevant, accurate and clear processing with appropriate uncertainty and correct units, graphs and tables.
6
Conclusion
A justified answer consistent with the analysis, scientific context and real-world implications.
6
Evaluation
Specific weaknesses, their relative impact and realistic improvements tied to those weaknesses.
Efficient study plan
Four passes, not endless rereading
Each pass has a different job. Stop when you can explain, compare and apply without notes.
1
Map
Read all 29 topic titles. Mark unknown concepts and HL-only material.
2
Learn
Use one topic at a time: concept → comparison → application → check.
3
Link
Connect physiology, biomechanics and psychology to the same performance problem.
4
Retrieve
Use past-paper command terms, data questions and timed writing.
