Examiner Insights - March 2024

Key feedback from Cambridge examiners on how students performed

Key Takeaways

  • Read questions carefully to understand the context and what is being asked.
  • Memorize essential definitions and chemical tests, including reagents and expected observations.
  • Practice interpreting data from experiments and drawing appropriate conclusions.
  • Pay close attention to the wording of questions, especially command words like 'describe,' 'explain,' and 'deduce.'
  • When calculations are required, show all working steps to maximize partial credit.
Paper 12 - Multiple Choice (Core)

Some candidates struggled with recalling essential terminology. Candidates should carefully consider the full meaning of statements in the options, as some may be partially correct. Certain questions regarding properties of ionic compounds, chemical changes (endothermic vs exothermic), halogens, and redox reactions proved challenging.

Study Tips:

  • Create flashcards with definitions of essential terminology.
  • Practice identifying redox reactions in different contexts.
  • Review the reactivity series and its implications for metal extraction.

Common Mistakes:

Q5 (Ions vs Atoms)
Choosing option D because they didn't recognize the significance of 'ion' rather than 'atom'.
Carefully read and understand the entire statement in the options, paying close attention to key words like 'ion' vs 'atom'.
Q6 (Properties of ionic compounds)
Guessing the answer, suggesting poor recall of ionic compound properties.
Review and memorize the key properties of ionic compounds.
Q7 (Properties of Graphite)
Choosing an option that describes a correct property of graphite but not its use as a lubricant.
Understand the relationship between a substance's properties and its specific applications.
Q9 (Relative Atomic Mass)
Not giving the relative mass of a proton relative to one twelfth of one atom of 12C
Remember that when asked to state the relative mass of a particle, provide its value relative to the standard (one twelfth of one atom of 12C).
Paper 22 - Multiple Choice (Extended)

This paper was accessible with many candidates performing well. The most demanding questions involved applying multiple concepts, such as identifying monomers and linkages in polymers or understanding redox reactions in displacement reactions. Careful reading of longer statements and questions with multiple columns of information is essential.

Study Tips:

  • Practice drawing dot-and-cross diagrams for different compounds.
  • Review the rules for determining oxidation states of ions in compounds.
  • Create a table summarizing the key differences between alloys and compounds.

Common Mistakes:

Q6 (Molecular Structures)
Choosing option B, unable to use the boiling point information to identify methanal as a simple molecular compound.
Practice relating physical properties like boiling point to molecular structure and intermolecular forces.
Q10 (Ionic Charges)
Choosing option B, not realizing Fe2O3 must contain two Fe3+ ions only and so it does not meet the description of magnetite.
Ensure the overall charge of a compound is zero, and apply this when determining the ratio of ions in a compound.
Q15 (Stoichiometry Calculations)
Not recognizing that the balanced equation uses two moles of ethyne instead of one, causing the incorrect calculation using mole ratios.
Always carefully examine the balanced equation to correctly determine the mole ratios before performing calculations.
Q19 (Oxidation of Iodide)
Not knowing the colour change when aqueous iodide ions are oxidized to form aqueous iodine.
Learn the colour changes associated with common oxidation-reduction reactions, such as the oxidation of iodide.
Paper 32 - Paper 3 Theory (Core)

Candidates demonstrated good knowledge in matching substances to statements, simple calculations, balancing equations, and the kinetic particle theory. Challenges arose with chemical tests, pollution-based questions, and accurate interpretation of data-handling questions. Misinterpretations of the rubric and command words also hindered some candidates.

Study Tips:

  • Create mind maps connecting different types of pollution to their specific sources and impacts.
  • Practice drawing displayed formulas of organic compounds frequently.
  • Focus on learning key definitions and revisisting them during revision time

Common Mistakes:

Q2(b) (Chemical Tests)
Writing the wrong test, getting mixed up between tests, or not writing a chemical test at all, and writing incorrect observations.
Practice and learn all the chemical tests, including reagents and expected observations.
Q2(d) (Pollution)
Giving vague answers about sewage or phosphates being harmful, instead of specifying the actual impact.
Describe the specific impacts of pollution (e.g., sewage causes disease, phosphates reduce oxygen in water).
Q2(e)(i) (Displayed Formula)
Struggling to draw the displayed formula of ethanoic acid, especially showing the covalent bond between the oxygen and hydrogen in the OH group.
Practice drawing displayed formulas, paying close attention to all covalent bonds.
Q3(a)(i) (Metallic Character)
Describing melting point, boiling point, density, outer electrons and reactivity rather than stating the trend of changes in the metallic character of the elements across a period
Focus on understanding the definition of each property and relating it to trends in the periodic table.
Paper 42 - Paper 4 Theory (Extended)

The overall standard was high, but some candidates were not familiar with the newer content of the syllabus. Candidates need to be careful in the use of subscripts in formulae and upper/lower case in symbols and read the question carefully. Calculations were generally done well but some candidates did not secure partial credit through lack of working.

Study Tips:

  • Review sections in syllabus, especially on the new content.
  • Practice writing ionic equations for precipitation reactions.
  • Review the rules of solubility for common salts.

Common Mistakes:

Q1(b)(i) (Percentage Calculations)
Assuming the total mass of iron within Fe2O3 was 56 (instead of 112) or to use the atomic number of Fe rather than the relative atomic mass.
Be careful to consider subscripts when calculating formula masses and use the relative atomic mass.
Q2(d)(i) (Covalent Bonding)
Stating that 'when two or more atoms …’ or ‘when two or more electrons …’ are involved in covalent bonding, instead of two atoms sharing two electrons.
Remember that a covalent bond involves a pair of electrons (two electrons) shared between two atoms only
Q2(d)(ii)(iii) (Halogens and Halides)
Stating iodine (a halogen) instead of iodide (a halide) and not stating what bromine was more reactive than.
Distinguish carefully between halogens and halides, and be specific when comparing reactivity.
Q2(g)(i) (Solubility Rules)
Not knowing the rules of solubility of salts and stating 'lead bromide' rather than 'lead nitrate'.
Memorize and apply the solubility rules for common salts.

0620 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 0620 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.
