Announcement:
Cambridge International Education no longer be an Ofqual-recognised awarding organisation from December 20, 2024.
O-Level is the abbreviation of Ordinary Level. It is one of the two-part GCE (General Certificate of Education). The second part of GCE is Advanced Level (A-Level), which students enter after completing O-Level.
O-Level is the final certification for secondary school, to be taken at fifth form or year 11 at approximately age 17 (or age group 14-16). Students that have completed O-Level are considered to have completed formal education. They can further their studies to A-Level (at their schools’ sixth form or private colleges), Foundation Courses or diploma courses, or simply leaving school.
There are a few exam bodies offer O-Level, for example CAIE board, American Council for Higher Education and Edexcel International. Though schools in the UK had replaced O-Level with GCSE in 1988, it is still used in many Commonwealth countries, such as Bangladesh, Brunei, Malaysia, Malta, Mauritius, Pakistan, Singapore, Sri Lanka and also in Trinidad and Tobago. (Some schools in the UK have reverted back to exams based on O-Level at the later stage.)
O-levels are predominantly exam-based. Therefore, this is advantages for students in part-time or evening education. Some commentators criticised this mainly exam-based approach as offering only partial proof of the student’s overall ability in comparison with other methods (e.g., coursework-based assessment). There was no summative “school certificate”: each subject was a separate O-level in its own right.
(Below are the information for O Level from the CAIE exam board only.)
Cambridge O Level
Cambridge O Level is an internationally recognised qualification equivalent to Cambridge IGCSE and the UK GCSE. It provides learners with excellent preparation for academic progression to Cambridge Advanced as well as other progression routes.
Cambridge O Levels has been designed especially for an international audience. They are sensitive to the needs of different countries and for learners whose first language may not be English. The curriculum also enables teaching to be placed in a localised context, making it relevant wherever you teach it.
In some parts of the world, schools use Cambridge O Level as an international alternative to the local national examination.
Subjects
You can choose from more than 40 subjects in any combination to provide the building blocks to create your own curriculum. Students normally take 7-9 subjects in the O-Level exam, with maximum allowable 14 subjects.


Many schools allocate a total of about 130 hours for each Cambridge O Level subject, but how much time a school devotes to each subject will depend on a variety of factors. Though Cambridge sets the syllabus, but the school decides on the method of teaching. Candidates must enter for Cambridge O Levels through a registered school or exam centre. Your school or exam centre will be able to give you more details about how candidates work towards these assessments.
At school, more able candidates may study six or seven subjects at Cambridge O Level, but less able candidates may have a much more modest programme. In order to follow a broad and balanced curriculum, most candidates take courses from each of the five Cambridge O Level groups (Languages; Humanities and Social Sciences; Sciences; Mathematics; and Business, Creative, Technical and Vocational). However, it is also possible to study individual Cambridge O Level subjects if this better suits the candidate’s needs.
Cambridge O Level courses usually take two years to complete and exams are taken at the end of that period.
Assessment
Assessment takes place at the end of the course and includes written, practical and oral assessment. This broadens opportunities for students to demonstrate their learning, particularly when their first language is not English.
Grades are benchmarked using six internationally recognised grades, from A* to E. Therefore, it has clear guidelines to explain the standard of achievement.
Grade A* is awarded for the highest level of achievement, and grade E indicates minimum satisfactory performance. Grade U (Ungraded) is commonly regarded as fail.
Cambridge O Level examination series occur twice a year, in June and November. Results release is in August and January.
Recognition
Many universities worldwide require a combination of Cambridge International A Levels and Cambridge O Levels to meet their entry requirements. Leading US and Canadian universities require Cambridge International AS & A Levels, but some US and Canadian colleges and universities will accept learners with five Cambridge O Levels at grade C
or above.
In the UK, Cambridge O Level is accepted as equivalent to the GCSE. Many UK universities look at Cambridge O Level grades, as well as predicted grades for Cambridge International A Level, when making admissions decisions.
Universities in many countries, including Canada and the USA, will admit students on the basis of their Cambridge O-Level performances alone. Grade C in Cambridge O-Level English Language satisfies the English proficiency requirements of many universities in the UK and other English-speaking countries.
Difference between Cambridge IGCSE and O Levels
Although IGCSE and O Level are equivalent qualifications grade for grade, they are two different qualifications. IGCSE sets international standards, on the other hand, O Level syllabus meets specific local needs in each country. Other notable differences are the grading scale, assessment techniques, and coursework options.
| IGCSE | O Level | |
| Grading | Grades are awarded from A* (highest grade) to G (lowest) | Grades are awarded from A* to E |
| Assessment techniques | Tests oral and practical skills | Focuses on writing and reading skills in language subjects Restricted practical test options in sciences |
| Coursework options | Available in many syllabuses | Fewer coursework options |

Why grade F is considered fail in GCSE but not in Igcse
Hello Arnob,
Grade F is still an awarded qualification in GCSE. But it does not meet the standard pass requirement of the Department for Education of UK, which is why they considered it as a fail.
The same goes for IGCSE, although you earned a qualification and passed with a grade of F, the mark is too low that when you apply for A Level and university, they may not accept it. Thus, even if it is not explicitly regarded as fail, the performance is very unsatisfactory that a retake is highly suggested.
Does edexcel requires to submit igcse grades before registering to A level
Hello Arnob,
Please contact the exam centre where you will be registering for the exam for the registration process.
Thank you.
I got grade G in accounting so can I register for accounting a level as a edexcel private candidate without restrictions
Hello Arnob,
As a private candidate, we suggest that you contact your exam centre where you plan to register for the exams.
Because as far as we know, there are schools and exam centres that require grade C and above when you register for that specific subject at A Level.
In your case, since you received a grade below C at IGCSE Accounting, you may ask your exam centre directly if they will accept your registration for A Level Accounting.
Thank you.
I got grade u in edexcel igcse economics so can I register for A level economics because I don’t want to retake igcse economics

Thank you.
