IGCSE Biology Structured Questions Exam Tips

Learn how to write step-by-step answers, and score A* in your exam!

Announcement: Cambridge IGCSE, and AS & A Level November 2024 past papers are now available.

Papers 3 (Core) and 4 (Extended) are composed of questions that require short answers and extended writing. It is expected that there is more to read in these papers as the whole question often includes stimulus materials and parts. This tests the candidates’ ability to demonstrate their knowledge and to apply the concepts in their response. Through this article, candidates will be guided on how to draft their answers properly.


Basic guidelines

  1. Don’t waste time by writing out the question before answering. Answer directly and don’t write things that are unrelated to the question.
  2. Look for clues in the keywords of the question to help you identify which part of biology is being tested.
  3. The whole stimulus material is relevant. You must read all the information given carefully. This is often different from what you’ve studied but there’s enough information in the question to work out an answer. For example, if the question includes a food web as its stimulus material, you must apply your response to the food web shown in the diagram and not from other food webs you’ve learned.  
  4. The number of marks helps you decide how much to write and guides you how long to spend on each question or parts of a question.
  5. Only give the number of answers that are asked. Use the numbered lines and give one answer per line.
  6. If there are two or more marks don’t write the same thing in two different ways, e.g. ‘The leaf is very large. The leaf has a large surface area’. The second sentence is more accurate and is preferable to the first one.

Read the question carefully and use the information given

The question set usually includes all the stimulus material and parts (a), (b), (c) (i) and (c) (ii), etc.  Read them carefully before answering them. All the information applies to the question. The question will tell you what material will be used or where you will take the information from. You will not earn marks if you take the irrelevant information.

The stimulus material may be in the form of diagrams, graphs and tables. Study diagrams, such as a food web, a set of apparatus or a biological structure. Analyse graphs which could be a line graph, a bar chart or a histogram. Read tables and always check for the heading and units. You might be unfamiliar with the new information but do not hesitate. This tests  your ability to apply knowledge to new information. Follow the same advice as before. There will always be enough information in the question to answer it. Look for clues that will help you identify which part of the syllabus the question is about.

I’ve learned advanced things much faster than a teacher could have taught me

“I am really enjoying Skolatis! It is very helpful. I feel that the way you teach the subjects are very helpful and aid in helping people learn more complicated things. For example I’m a lot ahead in chemistry and biology. I’ve learned many more advanced things much faster than a teacher could have taught me it. Skolatis has really helped me improve in chemistry and biology.”
~ James Armenis (Greece)

Be wary of command words

Command words are used to guide the candidates on what is being asked as it provides the context on what must be included in the answer.  You must review all the command words to have an idea of what to answer. The table below lists the terms used in biology papers and how to respond to each command word. These can be found at ‘Glossary of terms used in science papers’ towards the end of the syllabus.

Command wordWhat it means
Calculatework out from given facts, figures or information
Compareidentify/comment on similarities and/or differences
Definegive precise meaning
Describestate the points of a topic / give characteristics and main features
Determineestablish an answer using the information available
Evaluatejudge or calculate the quality, importance, amount, or value of something
Explainset out purposes or reasons / make the relationships between things clear / say why and/or how and support with relevant evidence

Predictsuggest what may happen based on available information
Sketchmake a simple freehand drawing showing the key features, taking care over proportions
Stateexpress in clear terms
Suggestapply knowledge and understanding to situations where there are a range of valid responses in order to make proposals / put forward considerations
Command words

Write the biological terms accurately

There are specific biological concepts and terms that you must understand and use correctly in your response. Most of the terms are defined in the syllabus and that is a good place to learn all the definitions. It may be best to make a list of the terms using the glossary found in the syllabus to familiarise the meaning of these words.

It is also important to use the correct spelling of the terms. No marks will be given if your spelling is too far out but there are cases where examiners will try to discern your wrong spelling. You must also keep an eye on biological terms that have similar spelling. One example is ‘ureter’, ‘urethra’ and ‘uterus’. If the answer is ureter, and it was misspelled to ‘uretus’, it is not clear enough as it could have thought the answer is ‘uterus’. Also, don’t try to mix the spellings of two words when there’s uncertainty on which one of them is the correct answer. For example, writing ‘urether’ as an answer when indecisive on which is the correct answer between ureter or urethra.

Communicate your response properly

The papers often ask to write common and complicated terms in biology and it is not only understanding the concepts that are significant but also how it will be conveyed in the response.  Make sure the answers are clear and easy to read to avoid confusion. Aim to write in short sentences rather than long sentences. Writing lengthy response is prone to contradictory statements and muddled answers.  

You must write a clear explanation if you are using the words ‘it’, ‘they’, ‘effect’, ‘affect’. A sentence like ‘It has an effect on the body’ or ‘They affect the process’ does not say anything. If you would be using the word ‘it’ or ‘they’, you must specifically state what you are referring to. On the other hand, if ‘affect’ or ‘effect’ would be used, write the impact or the outcome that they would have caused.

Me and my brother were not good at English from the start. Luckily we got to know about Skolatis revision courses from one of our friends. My brother purchased the English course from his account and we gave our best to improve our English. The course was fantabulous. The videos explained the concepts so well that there was no doubt in us getting an A* in English in 9th Grade.

My daughter Nawal Amir completed her english revision course with igcse center. Words cannot define how comprehensive and supportive the whole course is. The administration and the teachers are prompt and methodical in guidance. Not only that being a parent one doesn’t have to worry about how is the progress of their children as they go according to a timetable with test papers practice along with it. I
wish best of luck to igcse team and a great lot of thanks to Leana especially.

  1. Hello IGCSE center,
    What are the abbreviation that can be accepted wben the student answer a structured question. For example conc for concentation or temp for temperature. Are these accepted? If yes can you tell me the list of accepted abbreviations. Thank you.

    1. Hello Salma,

      Thank you for writing in.

      Always try to write accurately using the correct biological terms. Candidates often lose marks because they don’t use the vocabulary of biology correctly.

  2. Hi IGCSE centre,

    I have a little request/question: could you please give me some tips on how to draw a perfect table and score full marks in that question in Biology Paper 6?

    Thanks.

    1. Hello Abide,

      The construction of a table should be done with ruled lines, preferably with an outer border. Units need to appear in the headings and not in the cells of the table. Each item of information needs to be in a discrete cell.

      Furthermore, use a sharp pencil and eraser for drawing tables, diagrams, and graphs. Mistakes can then be rectified and necessary additions made very easily. Drawings should be neat, in proportion, and show sufficient detail.

      Should you need further assistance, feel free to write to us. Thank you.

        1. Hello Abide,

          Read the question very carefully – it may give you guidance on what your table should be.

          Furthermore, each column should be headed with the physical quantity and the appropriate unit, e.g. time / s while the column headings of the table can be directly rewritten on to the axes of a constructed graph.

  3. Hi IGCSE centre,
    how many points should I write for a 4 marks question. In the marking scheme, it has not mentioned. In some marking schemes its written write any 4 points out of the given points. So marks = number of points given.

    1. Hello Shaina,

      Yes, you are right. For example, if a part of a question is worth four marks you should make four separate points. Be careful to not to repeat the same point.

      Furthermore, do not do more than what is required. For example, if two reasons are required, do not provide four. You will not lose marks but you will lose time. In such a situation, the examiner will usually take the first two answers; the examiner will not select the correct answers from your list.

      We hope this helps. Thank you.

    1. Hello Azamek,

      CAIE announced that they continue to plan for exams to go ahead in June 2021 where it is permitted and safe. But for small number of countries (such as Mexico and the UK) and regions within countries where running exams is not possible because of directives from national or regional authorities, CAIE is looking at switching from exams to an approach based on teacher assessment. This would apply to all schools in those countries and regions.

      We suggest that you keep in touch with your exam centre for any changes. Thank you.

    1. Hello Takudzwa,

      Here are some tips for you:

      Biology Alternative to Practical:

      – Read through the questions carefully, looking to see how many marks are given for each question

      – Make sure that you have done plenty of practical work so you can imagine what has happened to obtain the results that you will process, analyse and interpret in the questions

      – Make sure that you have a sharp pencil to use for making drawings and drawing graphs and charts. Don’t draw in ink because you can’t make changes as you can when using a pencil

      – Write down exactly what you see – as differences or similarities. Measurements may need to be made and magnifications calculation.

      – Use one clear continuous outline not an artistic drawing. Don’t shade other than using very light dots

      – Make your measurements as accurate as you can. Measure to the nearest unit, e.g. mm. Don’t try and ‘guess’ 0.5 mm.

      Physics Alternative to Practical:

      – It is important to be able to set up a circuit from a diagram, draw a circuit diagram of a circuit already set up and also to draw a circuit diagram from a written description.

      – Column headings in tables of readings must be headed with the quantity and unit as in these examples: I/A, or t/s, or y/m. Graph axes are labelled in the same way

      – You should understand the significance of wording such as ‘within the limits of experimental accuracy’.

      – If you are asked to justify a statement that you have made it must be justified by reference to the readings. A theoretical justification in a practical test will not gain marks.

    1. Hello Mohamed,

      As far as we know, CAIE is still planning for the November 2020 exams to go ahead. CAIE also recognises that the covid-19 pandemic will continue to create uncertainty this year, in different countries at different times. They are developing our contingency plans and they will keep centres up to date in the coming weeks and months.

      We suggest that you contact your school/exam centre for any changes. Thank you.

    1. Hello there,

      As far as we know, Cambridge International is planning to run exams for the November 2020 series. They are continuing to monitor advice from government authorities around the world on whether schools can open and exams can be held in October/November. Cambridge International’s regional teams are also in close contact with their schools.

      We suggest that you keep in contact with your school/exam centre’s for any changes. Thank you.

  5. Hello IGCSE Centre! My name is Varshith and I’m from India. My boards are in February and March 2020. I’m pretty weak in Maths(0580) Paper 4, Chemistry(620) Paper 4, English(0500) Paper 2[Compostions] and French Paper 3 and 4(0520). Can you give some tips for improving in these subjects, where I feel I lose most of the marks in those areas. Please can you give any tips and advice?

    1. Hello there,

      We suggest that you start your revision as early as possible. Highlight the important facts that you think could be on the test (you should refer to the latest syllabus on what is expected during exams here: https://www.skolatis.com/cambridge-igcse-subjects-syllabuses/). You can then use the past exam papers (https://www.skolatis.com/cambridge-igcse-past-exam-papers/) as your revision. Start with the latest papers as they have the newest syllabus format and continue with the older ones date back from 5 to 10 years. Then, revise on the most common mistakes that you always seem to make. Pay attention to the most common mistakes you always seem to make. Make notes and revise them, so you can avoid making the same mistakes in your actual exam.

      Along the way of studying, our A* exam model answers might help in learning how to write A* answers. Many students scored A* by copying the style of the answers. Please check them out here: https://www.skolatis.com/igcse-exam-resources/.

      Hope this helps.
