How CIE marks the exam scripts?

Most of the exam scripts are scanned and marked by the examiners on their computer. Other exam scripts are marked manually on paper. For the multiple choice component, the computer automatically marks the papers.

Who marks the exam scripts?

Cambridge examiners are composed of teachers and subject experts. Their task is to mark the exam scripts at the same standard. This means all the examiners mark according to the mark scheme and they all apply the mark scheme in the same way.

How does the CIE standardise the marking?

A team of experienced senior examiners mark sample set of exam scripts based on the mark scheme. They then agree to the marks. These same exam scripts set the standard and will be used by the other examiners to practice marking. This is to make sure that all examiners understand how to mark the same way. For the final part of calibration, they mark another set of scripts as a test. They then begin to start marking all other papers.

The senior examiners review all the markings of every examiner. This is to ensure that they are all marked correctly. If an examiner fails to mark consistently, another examiner remarks the scripts.

How do they turn mark into grade?

CIE uses grade boundaries to convert marks into grades. The grade boundaries are the minimum mark needed to achieve a grade. It considers statistical evidence and expert judgment to agree to grade boundary. It also accounts the slight difference in the level of difficulty every year.

When the grade boundaries are set, it is applied to marks for grading. The senior examiners carry out final checks on the markings and the results are then sent to the schools.

How to convert component marks into syllabus grade?

From Raw Mark to Syllabus Grade Chart


Step 1: Find the component’s raw mark

The raw mark is the sum of all the total marks achieved in that component.

The mark found on the candidate’s completed examination script is the raw mark. For example in Syllabus 0620, the candidate’s raw mark in Component 41 is 20 out of the 80 total marks available.

Finding Raw Mark


Step 2: Adjust raw mark

Raw marks are adjusted to ensure fairness and equality. It can be adjusted due to scaling, granting of special consideration or both. Scaling is applied to ensure consistency across the marking process and the different examiners. Special consideration is granted if CIE agrees to an earlier formal request from a Centre. Usually, there is no need to adjust marks and the mark stays as raw mark.

For example, the candidate’s component 41 raw mark of 20 is adjusted to 21 to reflect the fairness and consistency of marking between examiners.

Adjust Raw Mark


Step 3: Find the component grade

Compare the component’s raw mark with the component’s grade thresholds. The component grade can be found on the subject syllabus’ Grade Threshold.

For example, the candidate’s component 41 adjusted mark is 21, its component grade falls under the grade D threshold.

Finding the Component Grade


Step 4: Calculate final mark and syllabus total

Calculate the final mark by multiplying each component’s mark by its weighting
factor. Weighting factor is the value assigned by CIE to indicate the level of importance of each component. The component weighting factors can be found at www.cie.org.uk/weighting.

Calculate the syllabus total by adding all final marks together. Round up syllabus totals that end in 0.5 to the nearest whole number.

For example, the candidate’s component 41 adjusted mark (21) is multiplied by the component’s weighing factor which in this case is 1.25. This will lead to the candidate’s component 41 final mark of 21 x 1.25 = 26.25.

Weighting Factor

Multiplying the Component Weighting Factor

Consequently, when all the component’s final mark is computed, the candidate’s syllabus total can be calculated by adding it. For example, the candidate’s final marks for each component are 28.5, 26.25 and 20 for Components 21, 41 and 61 respectively. The sum of all of these component marks totals to 74.75. It is then rounded off to the nearest whole number that is 75.

Adding Components Final Marks for Syllabus Total


Step 5: Find the syllabus grade

Compare the syllabus total to the overall grade threshold. Make sure that the option code is correct. As the grade thresholds for different options may not be the same.

For example, if the candidate took the combination of Components 21, 41, and 61, the syllabus grade should be compared to Option CX grade threshold. As such if the candidate’s syllabus total is 75, it falls under the Grade D threshold because Grade D threshold are for 71 marks and above. The Grade C threshold is for marks that are 84 and above.

  1. I am applying for 2019 feb-march exams ,so i want to know on which topic should i focus in chemistry,biology,physics ,business studies and maths .
    And also in India which question paper does student write p22,42,62?
    Please help me with my concern

  2. what if I get a mark of 75 in my results saying it is a B on the results sheet but according to the grade boundaries 75 is an A*

    • Hello,

      The statement of results shows your percentile not your mark. The numbers shown in a bracket is the percentage uniform mark (PUM). It corresponds to the grades available (A*, A, B, C etc.) and gives students additional information about their performance. They show students whether they are in the middle of a grade or near the top or bottom.

    • Hi Victor,

      The instruction clearly states “Do not write in any bar codes” The computer may not be able to scan your paper.

  3. Hi,
    How are the Grade Thresholds made for an exam? I gave Paper 62 for International Mathematics (0607) and I found it extremely challenging and difficult. Some of my peers left the question paper blank! So I wanted to enquire whether or not the grade boundaries will drop? If they will plummet, then by how much?
    Thanks.

  4. I am giving my exams privately. So how can i see the timetable of may june. and the threshold of 2017 oct nov.

  5. if i pass one paper lets just say like evm has 3 papers ok. i failed 1 paper but the other 2 papers went good and the marks is above the thresholds so i will i pass when the percentage is calculated or will i fail. one more question do they calculate the marks from the papers individually or combining all the papers
    thanks

    • Hi Kohls,

      Each subject has different component combinations. The marking and grade threshold is being calculated as the article stipulated above.

      You may take any sample marks that you have from school, follow the above steps, and work out your final total marks and grade.
