Life & Earth Sciences Exam Prep 2026
Prepare for the life & earth sciences exam (coefficient 6, 3h30 paper) with AI-generated study sheets, quizzes & flashcards.
Life & Earth Sciences exam format
The Life Sciences exam has two exercises. Exercise 1 is an organized knowledge synthesis or essay question (~1h30), often with a diagram to draw. Exercise 2 is scientific reasoning from documents (~2h): analysis of experimental results, data interpretation, problem-solving. Diagram quality and scientific reasoning rigor are key.
Life & Earth Sciences program for 2026 exams
The Life Sciences curriculum covers three major themes. Earth, life and living organization: genetics, DNA, gene expression, mutations, biodiversity. Contemporary planetary challenges: ecosystems, biogeochemical cycles, climate change, evolution. Human body and health: immune system, myotatic reflex, nervous communication, reproduction. Experimental methodology and data analysis are central.

Tips to succeed in the life & earth sciences exam
Diagrams are worth many points in biology. Practice drawing key diagrams (cell cycle, synapse, immune response) with a title, legend, and clean arrows.
For reasoning exercises, always follow the approach: observation, hypothesis, document analysis, conclusion. Connect each document to your answer.
Create study sheets with precise definitions of scientific terms. In biology, vocabulary precision is graded.
Review lab work and experimental protocols. Questions often focus on experimental methodology: tested variables, controls, expected results.
Use functional diagrams to synthesize complex mechanisms (immune response, blood sugar regulation). They help both understanding and exam performance.
Common mistakes in life & earth sciences
Avoid these classic pitfalls to earn more points on exam day.
Confusing correlation with causation in document analysis. A graph showing parallel curves doesn't prove a cause-and-effect relationship.
Drawing diagrams without titles or legends. An unlabeled diagram loses nearly all its points. Always title, label, and add arrows.
Neglecting partial conclusions. After each document analyzed, formulate an intermediate conclusion that advances toward solving the problem.
Frequently asked questions about the life & earth sciences exam
How to succeed in the biology exam?
Master key diagrams (cell cycle, synapse, immune response), learn scientific reasoning methodology (observation → hypothesis → analysis → conclusion), and practice with past papers. Well-drawn diagrams earn significant points.
Which biology chapters come up most often?
Genetics and gene expression, the immune system, and ecosystems/biodiversity are the most frequent topics. The myotatic reflex and biogeochemical cycles also appear regularly. Prioritize these 5 themes.
Are diagrams mandatory in biology exams?
Diagrams aren't always explicitly required, but they're highly valued. A good functional diagram can replace an entire paragraph of explanation and shows you understand the mechanism. Include at least 2-3 diagrams in each paper.
How to manage time in the 3h30 biology exam?
Spend about 1h15 on exercise 1 (synthesis) and 1h45 on exercise 2 (scientific reasoning), plus 30 minutes for review and diagrams. Start with the exercise you know best to secure points.
What is the biology exam coefficient?
Biology has a coefficient of 6 as a specialty exam in the general baccalaureate. It's a high coefficient that can make the difference for honors. Structured revision sheets and past paper practice are the keys to success.
