Edexcel IGCSE vs Cambridge IGCSE

Determining whether Edexcel IGCSE or Cambridge IGCSE is “better” depends on several factors, including your goals, future studies, and subjects availability. Edexcel IGCSE and Cambridge IGCSE are international qualifications with similarities in grading and subject offerings.

For schooled candidates

Edexcel IGCSE has a much straight forward approach, with only one type of paper combination for all learners. Thus, all learners have equal chances to score grade A* (or grade 9 with the new grading scale system).

Cambridge IGCSE has more (and rather complicated) paper combinations. Exam entries are based on teachers’ grade prediction towards the learners. Therefore, teachers’ predictions are often contradicting with what learners wish to achieve at final exams. Consequently, resulting in lower paper entries that prevent the learners to achieve higher grade in the exams. Learners have complaint not able to adjust exam entries in time, and are facing high level of stress.

Here is one of the many SOS messages:

“I actually I want to study medicine. So u know that universities needed grades like A* TO B.  but I knew the core grade’s maximum, so I shocked to hear that. If you imagine that I got the grade C but it is not related to the university requirements  so it is not possible to enter to my dream careeer. I also paid the fees for the IGCSE exam. Our school, also didn’t explained that clearer. Ok, So is there any ways to change the curriculum from core to extended. Any way or method (suggestion from you) “

IGCSE subjects and curriculum

Edexcel IGCSE subjects

Edexcel board currently offers 37 subjects for the International GCSE examinations. Edexcel’s iGCSE curricula are well established, and consistent throughout the learners’ learning journey. The curricula do not constantly change and thus learners can learn with peace of mind.

Learners may choose the subject combination based on their future studies in higher education.

Cambridge IGCSE subjects

Cambridge IGCSE offers more than 70 subjects. Students are required to take a minimum of 5 or maximum of 14 subjects. The core subjects are English, Mathematics and Sciences. Students can also choose other subjects ranging from Social Sciences (commonly Accounting, Business Studies, Economics, Sociology) to Arts & Technology (commonly Computer Studies, Information & Communication Technology (ICT), Art & Design).

Student is awarded with one IGCSE certificate on each subject. For example, you will obtain 5 IGCSE certificates, if you take 5 subjects. Each school decides upon the number of compulsory subjects differently. However, a private candidate may decides based on individual preference.

Edexcel iGCSE curriculum

Edexcel iGCSE curricula are well-established, stable and based on current international audience requirements. Besides that, they have more extensive and wide range of topics that are prerequisite knowledge prior to International A Level studies.

Example topics and chapters that are available in Edexcel iGCSE, but not in Cambridge IGCSE:

  • Edexcel had introduced Astrophysics since 2017, for first examination in 2019. Cambridge had just introduced Space Physics for first examination in 2023.
  • A large number of sub-topics that are available in Edexcel iGCSE but not in Cambridge IGCSE. Some examples are:
    • Chemistry: Solubility, Molar gas volume, Determine the formula of a metal oxide by reduction, Fullerenes, etc..
    • Biology: Homeostasis, Fungal cells, Variation within species, etc..
Cambridge IGCSE curriculum

Cambridge IGCSE curricula are regularly updated and extended on a yearly or every 2-year basis. Therefore, this has become a great challenge for learners, parents and teachers to catch up with the constant changes.

Example incident:
A teacher in a private school in the UK was not aware of the change of syllabus for English First Language. We managed to assist her with the new exam syllabus just 2 months prior to the exams.

In view of the constant change of Cambridge IGCSE syllabus, here at Skolatis, we have developed a system to keep updating our course material so that candidates are learning the right exam syllabus. Parents can have peace of mind that their children are learning the right syllabus.

Cambridge IGCSE Curriculum is divided into 6 main subject groups. Each group contains several subjects which learners can choose from, in order to fulfil the minimum required subjects.

IGCSE vs GCSE

IGCSE (International General Certificate of Secondary Education) and GCSE (General Certificate of Secondary Education) are both qualifications that students in the United Kingdom and many other countries can earn, typically during their secondary education.

The main difference between IGCSE and GCSE lies in their geographic scope, curriculum, assessment methods, recognition, and flexibility. IGCSE is more internationally focused and flexible, while GCSE is primarily used in the UK and follows the UK national curriculum. Therefore, students and parents should consider these differences when choosing the most suitable qualification for their educational goals and circumstances.

Geographic Scope

GCSEs are primarily taken in the United Kingdom, including England, Wales, and Northern Ireland. However, in Scotland, a different system of qualifications is used.

IGCSEs are designed for international students and are offered by Edexcel and CIE. They are not limited to the UK and are used in many countries as an international qualification.

Curriculum

GCSEs follow the national curriculum of the United Kingdom. The relevant examination boards (for example AQA, OCR, etc.) in each of the UK nations determine the content and assessment methods.

IGCSEs do not necessarily follow the UK national curriculum. They often have a more global perspective and can be more flexible in terms of the subjects and content offered.

Assessment

GCSEs in the UK are assessed through a combination of coursework (controlled assessments) and final exams. The grading system for GCSEs uses letter grades (A*, A, B, C, etc.).

IGCSEs typically rely more heavily on final exams, with limited or no coursework. The grading system for IGCSEs may use letter grades or a numerical scale.

Recognition

GCSEs are widely recognised within the United Kingdom and are the standard qualification for students in the UK education system.

IGCSEs are recognized globally and may be more suitable for students who plan to study abroad or want to have their qualifications recognized in multiple countries.

Flexibility

GCSEs offer less flexibility in terms of subject choices and the content of the qualifications. Students typically follow a prescribed set of subjects.

IGCSEs often offer more flexibility in subject choices, allowing students to tailor their education to their interests and needs.


Worldwide recognition

Universities and employers worldwide widely recognise and accept Edexcel IGCSE and Cambridge IGCSE qualifications.

Here are some examples international learners’ admissions into top universities globally.

Assessment methods

IGCSE vs O Levels

Although IGCSE and O Level are equivalent qualifications grade for grade, they are two different qualifications. IGCSE syllabus meets international standards while O Levels syllabus meets specific local needs in each country.

    1. Hello Simran,

      Please kindly check the key dates here: https://www.skolatis.com/exam-registration-dates/

      As far as we know, CAIE will use their usual approach to grading exams wherein they use a variety of statistical and judgemental methods. These methods help CAIE maintain the awarding standard from one year to the next. Furthermore, aligning the awarding standards ensures that the competition will be fair, without giving an unfair advantage or disadvantage to Cambridge candidates.

      We hope this helps. Thank you.

    1. Hello Dara,

      Our advice is to choose your subjects according to what you want to study in the university. The subjects will be based on the university’s subject entry requirements. As such, we strongly encourage you to first check with the university on the required subjects.

      We hope this helps. Thank you.

  2. Hi
    I want to take admission in As and a level in school but I am 20 yrs and the agr limit is 19..so can I really take admission? Is there a strict rule for age criteria.. plz reply

    1. Hello Aryan Seth,

      Thank you for writing in.

      Although AS/A Level are usually taken by 17 to 18 year old candidates, Cambridge does not set any specific age requirements. Furthermore, there are many adult candidates sitting for the A Level every year.

      We hope this helps. Thank you.

    1. Hello Shazoor,

      It is not compulsory for IGCSE students to proceed to A Level but it is highly suggested. This is because most of the universities accepts a combination of IGCSE and A Level certificates as their entry requirements.

      If you wish to pursue for further study, we would suggest that inquire directly to your chosen university for their entry requirements.

      We hope this helps.

    1. Hello Alana,

      Normally, universities require a combination of IGCSE and A Level certificates to gain entry. We would suggest that you inquire directly to your chosen university for their entry requirements.

      Thank you.
