Examiner Insights - March 2023

Key feedback from Cambridge examiners on how students performed

Key Takeaways

  • • Read the questions very carefully and ensure you are answering the actual question being asked.
  • • Pay close attention to definitions and key processes, ensuring you understand them thoroughly.
  • • Show your workings in calculations to enable partial credit where applicable.
  • • Be specific and precise in your answers, using appropriate scientific terminology.
  • • When planning experiments, focus on controlled variables, the aim, and suitable methods, rather than prediction.
Paper 12 - Multiple Choice (Core)

Overall, there was good understanding of magnification, food tests, and selective breeding. However, some uncertainty was observed in understanding the definition of excretion, water loss from stomata, and the identification of motor neurons. Students should carefully read the questions and methodically work through the given information.

Study Tips:

  • ✓ Read questions carefully to understand what is being asked.
  • ✓ Review definitions and key processes thoroughly.

Common Mistakes:

Q1 (Excretion vs. Egestion)
✗ Believing undigested food is removed by excretion.
→ Remember excretion is the removal of metabolic waste and excess substances; egestion removes undigested food.
Q3 (Insect Anatomy)
✗ Incorrectly identifying the number of legs on an insect.
→ Remember insects have three pairs of jointed legs.
Q6 (Diffusion)
✗ Believing increasing the concentration gradient would decrease the rate of diffusion.
→ Increasing the concentration gradient *increases* the rate of diffusion. Understand factors affecting diffusion: concentration gradient, surface area, temperature, and diffusion distance.
Q8 (Active Transport)
✗ Opting for the diagram showing particles moving from a region of higher concentration to a region of lower concentration.
→ Active transport moves particles from a region of *lower* to *higher* concentration, requiring energy.
Paper 22 - Multiple Choice (Extended)

There was good understanding of magnification, food tests, and the function of teeth. Some uncertainty existed regarding anaerobic respiration, phototropism, and the similarities between natural and artificial selection. Careful and methodical approach to the provided information is essential.

Study Tips:

  • ✓ Practice applying knowledge to different contexts and scenarios.
  • ✓ Review the syllabus definitions for key concepts such as phototropism and respiration.

Common Mistakes:

Q12 (Leaf Structure)
✗ Incorrectly identifying the cuticle as the epidermis.
→ Know the different layers of the leaf, including cuticle, epidermis, mesophyll, and vascular bundles.
Q16 (Transpiration)
✗ Opting for evaporation instead of diffusion as the process by which water escapes from stomata.
→ Water escapes from stomata via diffusion, following the concentration gradient from the moist leaf to the drier air.
Q21 (Seed Germination)
✗ Being uncertain about which gas is taken in by seeds and the direction of movement of the colored liquid.
→ During germination, seeds take in oxygen (for respiration) and release carbon dioxide.
Q26 (Phototropism)
✗ Not appreciating that inside a dark box phototropism cannot occur in the roots or the shoots.
→ Phototropism, the growth response to light, cannot occur without light stimulus. Roots and shoots require light exposure to show phototropic growth.
Paper 32 - Theory (Core)

Candidates performed well on short answer questions, but some found it difficult to express their ideas in longer answers. It's essential for candidates to read questions carefully and follow instructions, paying attention to the marks allocated.

Study Tips:

  • ✓ Pay close attention to the wording of the question and answer specifically.
  • ✓ Learn and understand the syllabus definitions for key biological terms.

Common Mistakes:

Q1(a)(v) (Balanced Diet)
✗ Stating food E contains all nutrients in the correct proportions without further explanation.
→ Specify why components such as carbohydrates, protein, and fiber are necessary and the benefits of low fats.
Q1(b) (Elements in Carbohydrates)
✗ Naming examples of carbohydrates instead of the elements present.
→ Remember carbohydrates contain carbon, hydrogen, and oxygen.
Q2(a)(ii) (Leaf Anatomy)
✗ Providing vague answers like 'plant cells' or 'leaf cells' instead of 'mesophyll cells'.
→ Be specific when naming structures; use the correct biological terminology.
Q3(a)(iii) (Dominant Inheritance)
✗ Stating 'we are told it is dominant' or 'it has a capital letter' instead of explaining the genetic proof.
→ Explain why the condition must be dominant based on the inheritance patterns from the provided pedigree. The actual proof lies in the fact that if the condition were recessive, then all the offspring of individuals 1 and 2 would have to inherit the condition
Paper 42 - Theory (Extended)

A high standard of scientific knowledge was displayed by many candidates. Some areas of the syllabus were better known than others. Candidates need to read questions carefully and use their knowledge to respond to the context.

Study Tips:

  • ✓ Practice labelling diagrams accurately, paying attention to the precise location.
  • ✓ Focus on questions that integrate knowledge from different parts of the syllabus.

Common Mistakes:

Q1(a)(i) (Blood Vessels)
✗ Identifying blood vessel A instead of B as the blood vessel transporting blood with the highest oxygen concentration.
→ Focus on the blood vessels directly leaving the lungs as being the most oxygenated
Q1(b)(ii) (Blood Pressure)
✗ Attributing changes in pressure to artery contraction/relaxation rather than heart action.
→ Understand that blood pressure changes result from heart contraction (increase) and relaxation (decrease). Muscular contraction influences this.
Q1(b)(iii) (Artery/Vein Structure)
✗ Simply comparing artery and vein structure without explaining structural adaptations (e.g. the purpose of elastic fibres).
→ State the structural adaptation and explain its importance: e.g. Arteries have thick walls *in order to* withstand high pressure.
Q4(a)(i) (Phloem Function)
✗ Describing phloem imprecisely as transporting 'glucose' or 'food' instead of the products of photosynthesis or sucrose
→ Understand the roles of the sink and source, and accurately describe what the pholem transports, i.e., the products of photosynthesis such as sucrose.

0610 Study Tips & FAQ

What are paper variants?

Cambridge releases multiple variants of each paper (e.g., Paper 11, 12, 13) to accommodate different time zones around the world and maintain exam security.

  • Variant 1 (e.g., 11, 21): Usually for Zone 1 (Americas)
  • Variant 2 (e.g., 12, 22): Usually for Zone 2 (Europe, Africa)
  • Variant 3 (e.g., 13, 23): Usually for Zone 3 (Asia, Oceania)

All variants cover the same syllabus and have similar difficulty. Practice with any variant to prepare effectively for your exam.

How to use Mark Schemes effectively

Mark schemes show exactly how examiners award marks for each question. Understanding them helps you write answers that earn full marks.

Example from a Physics mark scheme:

Q: Calculate the speed of a car that travels 150m in 5 seconds. [2]

Mark scheme answer:

• speed = distance / time [1 mark for formula]

• speed = 150 / 5 = 30 m/s [1 mark for correct answer with unit]

Tips:

  • Look for key words that must appear in your answer
  • Note how many points are needed for each mark
  • Check if units are required for the final mark
  • Understand the difference between "state" (brief) and "explain" (detailed)
Understanding Grade Thresholds

Grade thresholds show the minimum marks needed for each grade. They vary each session based on paper difficulty — harder papers have lower thresholds.

Example Grade Thresholds (out of 100 total):

A*
90+
A
80-89
B
70-79
C
60-69

* Actual thresholds vary by subject and session

How to use thresholds:

  • Set realistic target marks based on your goal grade
  • Track your practice paper scores against thresholds
  • Remember: you don't need 100% for an A* — aim for consistency
  • Compare thresholds across sessions to gauge difficulty trends
How is the topic breakdown calculated?

The "Topics Breakdown by Paper" section above shows which syllabus topics are tested in each paper and how many marks they carry. Here's how we calculate this:

Our methodology:

  1. Extract questions: We analyze each question paper (QP) and identify individual questions and their mark allocations (shown in square brackets, e.g., [3]).
  2. Match to syllabus: Each question is matched to the official Cambridge 0610 syllabus topics based on keywords, concepts, and question content.
  3. Sum marks per topic: For each paper, we add up the marks for all questions testing the same topic. For example, if Q1 (4 marks) and Q5b (3 marks) both test "Enzymes", that topic shows as "7 marks" for that paper.

Example: If Paper 3 shows "Photosynthesis - 13 marks", it means questions worth a total of 13 marks (out of the paper's 80 marks) tested the Photosynthesis topic from the Plant Nutrition unit of the syllabus.

How to use this: Look at the paper(s) you'll be taking (e.g., Papers 2, 4, 6 for Extended tier). The topics with the highest marks in YOUR papers are where you should focus your revision. A topic worth 15 marks deserves more study time than one worth 3 marks.

Note: Our topic matching may be inaccurate for questions that span multiple topics. Use this as a guide alongside the official syllabus.
