Doing London O/L alongside local O/L means sitting the national G.C.E. O/L at school, plus Cambridge or Pearson Edexcel exams taken privately through the British Council. Done well, it gives you an internationally recognised certificate without changing schools. Done badly, it means two exam seasons, two sets of fees and no rest. This guide sets out the dates for 2026 and 2027, which London series fits best around the local O/L, how many subjects is realistic and a term-by-term plan you can adapt.

What “London O/L” means

“London O/L” is the everyday name for three qualifications sat by private candidates in Sri Lanka:

• Cambridge O Level (for example Mathematics Syllabus D, 4024)
• Cambridge IGCSE (for example Mathematics 0580 or ICT 0417)
• Pearson Edexcel International GCSE (for example Mathematics A, 4MA1, or ICT, 4IT1)

Cambridge describes O Level and IGCSE as “equivalent qualifications grade for grade” (Cambridge International). If you are not attached to a school that enters candidates, you register as a private candidate with British Council Sri Lanka, which handles private entries for both boards and has offices in Colombo and Kandy. Our step-by-step guide to British Council private candidate registration in Sri Lanka covers documents, deadlines and fees. If you have not chosen a board yet, read Edexcel vs Cambridge O Level in Sri Lanka first.

Exam dates: London O/L and local O/L timing for 2026–2027

The local O/L has moved back to a December slot. The 2025 O/L was held from 17 to 26 February 2026, and the 2026 O/L is scheduled for 8 to 17 December 2026 (Daily Mirror, November 2025). The 2027 O/L is set for 7 to 17 December 2027 (NewsFirst, August 2026).

Exam	Dates	Source
Local G.C.E. O/L 2026	8–17 December 2026	Department of Examinations calendar, reported by Daily Mirror
Local G.C.E. O/L 2027	7–17 December 2027	Reported by NewsFirst
Cambridge IGCSE / O Level, Oct/Nov 2026 (Sri Lanka)	28 September – 13 November 2026	British Council Zone 4 timetable
Edexcel International GCSE, Nov 2026	27 October – 19 November 2026	British Council IGCSE timetable
Cambridge and Edexcel, May/June	Main summer series; 2027 dates not yet on the British Council site	British Council Sri Lanka

Two points catch families out:

• There is no January International GCSE series in Sri Lanka. British Council’s January 2027 Edexcel registration is for International A Level only (British Council Sri Lanka). Pearson’s 2026/2027 manual lists International GCSE entries for November 2026 and June 2027 (Pearson subject availability).
• Registration closes months before the exams. For May/June 2026, the Cambridge normal window ran from 18 December 2025 to 13 February 2026 (British Council fee list) and the Edexcel window to 13 March 2026 (British Council fee list).

What about the education reforms? Grade 6 reforms were deferred to 2027 after protests in January 2026 (Ada Derana, January 2026). The latest reports cover Grade 1, Grade 2 and Grade 6, with the Grade 2 and Grade 6 changes planned from January 2027 (The Morning, August 2026). None of them mention the O/L, so plan around the December dates above.

Which London series fits around the local O/L

You have three realistic choices.

1. May/June of your O/L year (recommended for most). You sit London subjects about six months before the local O/L. Revision for shared subjects such as Maths pays off twice, and you finish the London exams with a full term left for local-only subjects like religion and history.

2. October/November of your O/L year. The Cambridge timetable ends on 13 November and Edexcel’s on 19 November, three to four weeks before the local O/L starts. It works for strong students taking one or two London subjects. It is risky for anyone taking more, because the run-up to December is when schools hold term tests and final revision.

3. May/June after the local O/L. You focus on the local O/L first, then use the months before A/L classes start to sit London subjects. This suits students who decide late, but you lose the overlap with school teaching.

You can also split: one or two subjects in May/June, then the rest after the local O/L. Fees are charged per subject, so splitting costs no more than sitting everything at once, apart from any fee rise between series. The Edexcel International GCSE standard fee, for example, went from LKR 42,600 in May/June 2026 to LKR 45,500 in October/November 2026.

How many London subjects is realistic?

For most students taking the full local O/L, two to four London subjects is a sensible range. Choose them in this order:

1. Subjects you already study for the local O/L. Maths and English are the usual starting points. Put the London syllabus next to your local textbook: wherever the topics match, one round of revision serves both exams, even though the papers are styled differently.
2. Subjects that matter for your next step, such as English if you plan to study abroad or ICT if you are heading towards computing.
3. Only then, extras. Every additional subject adds a full fee and another set of past papers.

A few rules to know before you choose:

• You cannot sit Cambridge IGCSE Mathematics 0580 in the same series as International Mathematics 0607 or O Level Mathematics 4024 (British Council subject information).
• Late entry is not possible for subjects with coursework, practical or speaking components, which includes Edexcel ICT (British Council Edexcel information sheet).
• Some practical options for the sciences are closed to private candidates, so you take the written alternative instead. For Cambridge IGCSE Physics 0625, options BY and FY are not accepted from private candidates (British Council Cambridge information sheet).

A term-by-term plan for London O/L and local O/L together

This example is for a student in Grade 10 now who sits the local O/L in December 2027 and three London subjects (Maths, English and ICT) in May/June 2027. Shift the months if your school calendar differs.

Period	Local O/L focus	London O/L focus	Admin
Nov–Dec 2026	Keep up with Grade 10 work	Download the syllabus for each London subject and mark the topics your local textbook already covers	Watch the British Council site for May/June 2027 registration
Jan–Feb 2027	Normal schoolwork	Learn London-only topics, two evenings a week per subject	Register in the normal window and keep your payment confirmation
Mar–Apr 2027	Normal schoolwork	One timed past paper per subject each weekend; mark it with the mark scheme	Download your Statement of Entry and venue details when British Council emails you
May–Jun 2027	Light touch only	Sit the London exams	Bring a valid passport, NIC or Postal ID
Jul–Sep 2027	Full revision of all local subjects	Optional: start one extra London subject for after the O/L	Wait for London results
Oct–Dec 2027	Past papers and term tests; local O/L 7–17 Dec	None
Jan–Mar 2028	Wait for results	Register for any remaining London subjects for May/June 2028

A simple weekly rhythm during the London months: two short weekday sessions on London-only topics, one full past paper at the weekend, and one session going through your mistakes. Our guide to structuring IGCSE exam sittings as a private candidate has more on spacing subjects across series.

For past papers, start with the Edexcel IGCSE past papers for all subjects or, for Maths, the Cambridge 0580 and Edexcel 4MA1 past papers. If ICT is one of your subjects, our Edexcel IGCSE ICT Paper 1 and Paper 2 revision guide breaks down both papers.

What London O/L costs alongside the local O/L

Every London subject is a separate private-candidate entry, paid online in rupees by Visa or Mastercard. For the October/November 2026 series, British Council Sri Lanka charged (Edexcel fee list; Cambridge fee list):

Subject (Oct/Nov 2026)	Fee per subject
Edexcel International GCSE Mathematics A (4MA1)	LKR 45,500
Edexcel International GCSE ICT (4IT1)	LKR 50,400
Cambridge O Level Mathematics D (4024)	LKR 45,660
Cambridge IGCSE Mathematics (0580)	LKR 51,700
Cambridge late entry (Late Stage 1)	Fee + LKR 28,380 per subject

Three Edexcel subjects at the standard fee came to LKR 136,500 in that series. Registering on time matters: a Cambridge late entry adds LKR 28,380 to each subject.

Revision materials are the one cost you can keep low. Tutopiya Learning Portal Premium covers every subject and both boards for S$50 a year, about LKR 13,000, or S$10 a month (about LKR 2,600). A full year costs less than a third of one Edexcel entry. We converted at 1 SGD ≈ USD 0.78 and USD 1 ≈ LKR 333 (ValutaFX, average for 2–11 November 2026).

Frequently asked questions

Can I do London O/L and local O/L in the same year? +

Yes. The local G.C.E. O/L is scheduled for 8 to 17 December 2026 and 7 to 17 December 2027, while the Cambridge and Edexcel exams run in May/June and October/November. Sitting London subjects in May/June leaves about six months before the local O/L, which is the less stressful option for most students.

How many London O/L subjects should I take alongside the local O/L? +

Two to four is a realistic range for most students. Start with subjects you already study for the local O/L, such as Maths or English, so revision counts twice. Every extra subject adds a full private-candidate fee, which was LKR 45,500 for most Edexcel International GCSE subjects in the October/November 2026 series.

Is there a January series for Edexcel O/L in Sri Lanka? +

Not for International GCSE. British Council Sri Lanka's January 2027 Edexcel registration covers International A Level only. Pearson's 2026/2027 information manual lists International GCSE subjects for November 2026 and June 2027.

When do I register for the May/June London O/L? +

Registration opens months before the exams. For May/June 2026, British Council Sri Lanka's normal window ran from 18 December 2025 to 13 February 2026 for Cambridge and to 13 March 2026 for Edexcel. Check the British Council website for the 2027 dates, because they set the final deadlines.

Can I take Cambridge IGCSE Maths and O Level Maths in the same series? +

No. British Council Sri Lanka's subject information for November 2026 says candidates may not sit IGCSE Mathematics 0580 in the same series as International Mathematics 0607 or O Level Mathematics 4024. Pick one syllabus.

Do the 2027 education reforms change the O/L? +

The reforms announced so far start with Grade 1, with Grade 2 and Grade 6 reforms planned from January 2027. The reports do not mention changes to Grade 10, Grade 11 or the O/L, and the Department of Examinations has already scheduled the 2027 O/L for December.
