Easiest and Hardest Questions in the 2024 Exam
Analysing student performance data from the 2024 VCE Biology examiner report offers valuable insight into which questions students found most accessible—and which ones proved the most challenging. Understanding these patterns can help future students refine their revision strategies and target content areas that require more focused preparation.
Easiest Question: Question 1 (Paper 1)
- Topic: Protein structure – identifying a molecule based on its structure
- Why it was easy: This question tested fundamental knowledge of biomacromolecules, asking students to recognise that a molecule with a quaternary structure is a protein made of amino acids.
- Performance: 90% of students answered this question correctly, suggesting that most students had a solid grasp of basic protein structure and terminology.
- Implication: This reflects well on student understanding of core molecular biology concepts and indicates that these introductory topics are generally well-taught and well-revised.
Hardest Question: Question 3 (Paper 1)
- Topic: Gene regulation – attenuation in the trp operon
- Why it was difficult: This question required students to understand the specific regulatory mechanism of attenuation in prokaryotes—a process that involves simultaneous transcription and translation. It also required a detailed understanding of molecular interactions when tryptophan levels are high.
- Performance: Only 19% of students selected the correct response, indicating widespread confusion about the finer details of operon function.
- Implication: Gene regulation, particularly in prokaryotes, remains a challenging area for many students. The complexity of operon models and the subtlety of regulatory mechanisms like attenuation may require more targeted revision and clarification in class discussions.

What the 2024 VCE Biology Paper 1 Taught Us: Skills, Advice, and Common Mistakes
Paper 1 of the 2024 VCE Biology exam, made up entirely of multiple-choice questions, offered a snapshot of how well students had mastered the foundational knowledge and scientific thinking required by the study design. The examiner’s report reveals key insights that students should use to sharpen their preparation for future exams.
Key Skills to Focus On for VCE Biology Paper 1
While Paper 1 primarily tests content knowledge, it also requires students to engage with stimulus material and apply science skills. The most critical areas for students to strengthen are:
- Knowledge of Core Biological Concepts
- Topics like protein structure, cellular respiration, and immune response formed the basis of many questions. Students should revise not just definitions, but also understand processes and relationships between key terms.
- Interpretation of Diagrams and Graphs
- Many questions (e.g. Questions 8, 9, and 12) required students to extract and apply information from stimulus material. Accurate graph reading, especially when linked to experimental contexts, was essential.
- Scientific Literacy and Precision
- Students needed to distinguish between similar-sounding terms and apply precise understanding of concepts such as gene regulation, enzyme action, and modes of immunity.
- Understanding of Experimental Design and Scientific Method
- Several questions (such as 13, 18, 23, and 24) assessed students on how well they understood key experimental principles—like identifying controlled variables, study types, and interpreting primary data.
Examiner Advice for Students
The report also offered advice to help students make the most of their time and avoid unnecessary errors:
- Read Carefully and Use Logic
- The multiple-choice format rewards logical deduction as much as content recall. Students should be wary of rushing through questions that appear straightforward at first glance.
- Revisit Stimulus Material Before Answering
- When questions include a graph or diagram, students should take time to review the axes and trends carefully before jumping to conclusions.
- Practice Past Papers Under Timed Conditions
- The exam’s time pressure means that familiarity with question structure can give students a clear advantage. Regular timed practice helps build exam technique and speed.
- Use Reading Time Strategically
- Although Paper 1 is multiple choice, using reading time to preview the types of questions and stimulus material can help set the tone and strategy for the paper.
Common Mistakes Made in the 2024 Paper 1
Despite the accessible nature of many questions, the report noted consistent errors in student responses:
- Misinterpreting Visual Information
- For example, in Question 9, students often confused the locations of cellular respiration stages within the mitochondria. A clear understanding of organelle diagrams is essential.
- Lack of Understanding in Gene Regulation
- Question 3, on attenuation in prokaryotes, had one of the lowest correct response rates (only 19%). This suggests that students struggled with the finer details of gene expression control.
- Inaccurate Use of Scientific Terms
- Students occasionally selected distractors that sounded correct but didn’t match the scientific definitions—especially in questions involving CRISPR, immune response, and respiration.
- Over-reliance on Memorisation
- The exam tested understanding rather than recall. For instance, in Question 5, knowing the basic function of CRISPR wasn’t enough—students needed to understand the molecular interactions involved.
- Neglecting Science Skills Questions
- Many students underperformed on questions assessing scientific methodology, such as identifying variables (Q13) or interpreting types of data (Q23). These are core expectations of the study design and should not be overlooked.

Mapping of Paper 2 Questions to the VCE Biology Study Design
Paper 2 of the VCE Biology examination requires students to construct written responses, often integrating stimulus material and multiple parts. This mapping provides clarity on what each question assessed and how students performed. It can be used as a revision guide to pinpoint the most commonly assessed areas and to prioritise focus during exam preparation.
What We Learned from the 2024 VCE Biology Paper 2: Skills, Examiner Advice, and Common Errors
Paper 2 of the 2024 VCE Biology exam required students to construct short and extended written responses across a range of Units 3 and 4 topics. While many students showed solid understanding of content, the examiner’s report made it clear that strong performance also depends on how well students interpret, structure, and explain their answers in context. Here's what students can learn from this year’s assessment.
Key Skills to Focus On for VCE Biology Paper 2
Paper 2 assessed more than just content recall. The following skills were essential for success and should be a key focus for students preparing for future assessments:
- Interpreting and Responding to All Parts of a Question
- Multi-part questions (e.g. 4c) required students to respond to each component. Skipping or misreading parts led to lost marks, even when students had the correct knowledge.
- Scientific Writing and Clarity
- Responses needed to be logically structured and clearly communicate biological processes using appropriate terminology. Vague or overly brief responses often missed the mark.
- Connecting Concepts to Context
- Questions often provided experimental scenarios or case studies. High-scoring responses applied biological understanding specifically to the given situation, rather than using memorised answers.
- Using Data to Support Explanations
- Several questions required analysis of stimulus material, including graphs (e.g. Questions 4b, 5a, and 10a). Students needed to interpret trends and relate them to relevant biological processes.
- Understanding Mark Allocation
- Recognising that 2–3 mark questions require multiple pieces of information or a deeper explanation was crucial. Many students lost marks by writing answers that were too short or underdeveloped.

Examiner Advice to Students
The 2024 report offered the following practical recommendations:
- Use Dot Points Strategically
- Dot points are acceptable but must be complete. They should include key information and explanations—not just keywords or phrases.
- Plan Responses Before Writing
- Students who paused to plan their answers wrote more coherent and complete responses, particularly for extended questions.
- Incorporate Relevant Biological Knowledge
- The best responses embedded biological principles and concepts within their explanation (e.g. linking chlorophyll to its role in the light-dependent stage in photosynthesis for Q5a.ii).
- Be Familiar with Command Terms
- Understanding terms like describe, explain, justify, and compare was essential for targeting responses accurately and avoiding irrelevant information.
Common Mistakes Made in the 2024 Paper 2
The examiner’s report highlighted several areas where students consistently lost marks:
- Only Answering Part of the Question
- For example, in Question 4c, many students only addressed the second part of the question and ignored the first. Full marks were not awarded for incomplete answers.
- Repeating the Question Stem
- Responses that simply restated the question or used vague terms without elaboration did not demonstrate understanding and were often not awarded marks.
- Generic or Pre-planned Responses
- In Question 8c.ii, students gave memorised speciation answers without connecting them to the context of the populations provided. This led to a mismatch between the response and the question’s requirements.
- Underusing Graphs and Stimulus Data
- In data-based questions, students often failed to cite or interpret information from provided visuals. This weakened their explanations, particularly in extended responses.
- Insufficient Use of Biological Vocabulary
- Students missed opportunities to gain marks by omitting key terms or failing to describe processes with precision (e.g. using “stuff” or “thing” instead of specific terminology).
Conclusion
The 2024 VCE Biology examination offered valuable insights into what examiners expect and where students commonly go wrong. While many students demonstrated strong foundational knowledge, the examiners emphasised the importance of going beyond rote memorisation. High-performing students were those who could clearly explain biological processes, apply their understanding to new contexts, and think critically about experimental data.
As VCE Biology continues to assess both content knowledge and scientific skills, students should aim to balance their revision between mastering the syllabus and refining how they communicate their understanding. By focusing on the skills highlighted in the examiner’s report—and learning from the mistakes of previous cohorts—future students can position themselves for success in this challenging yet rewarding subject.
