O/L English Paper: 9 Mistakes That Lose Marks (and Fixes)

Sandun Ruwanpathirana · November 13, 2026 · 7 min read

Most students who fail to get a Distinction in O/L English don't fail because they don't know English. They fail because they repeat the same handful of avoidable mistakes under exam pressure. The list below covers the mistakes that show up again and again in practice papers, each with a specific fix.

If you can fix even six of these before your next practice paper, your mark goes up.

1. Writing the letter without the address

Paper II opens with a letter, and the first thing a tired student skips is the sender's address. That's two to three marks gone before the first sentence. Both formal and informal letters need the address and the date in the right place. Learn the format once and write it the same way every time — don't make up a new layout in the exam hall.

Fix: Decide on one layout you'll always use for formal letters, and one for informal, and drill them until you can write both from memory in under a minute.

2. Treating comprehension like a translation exercise

Students read the comprehension passage and try to translate every word into Sinhala or Tamil in their head. Then they run out of time. Comprehension doesn't test whether you understand every word. It tests whether you can find the specific information a question asks for.

Fix: Read the questions first, then go back to the passage looking for the answer. Underline the line where you find each answer. If a question asks "why," the answer is usually near the word because or the words so that.

3. One-word answers when a sentence is asked for

A question that says "Why did the writer go to Colombo?" needs a sentence. Writing "Doctor's appointment" loses half the mark. The marking scheme rewards full sentences on these questions more often than students expect.

Fix: If the question has the word why, start your answer with Because. If it has how, start with By. If it has what, start by repeating the noun from the question.

4. Writing dialogues as narration

Paper II often has a dialogue-completion question. Students write things like "He said that he was going home." That's narration. The question asks for the actual words of the dialogue — "I'm going home."

Fix: In dialogue questions, write exactly what each person says, in quotation marks, without "He said that..." Keep it conversational.

5. Ignoring the word count

The essay or short composition tells you a word range — usually 100 to 150 words for short pieces, more for the long one. Students either write 60 words (and lose structure marks) or 250 words (and lose relevance marks because they've padded). Both cost you.

Fix: Count the lines in your normal handwriting. Most students write 8 to 10 words per line. Use that to hit the range without actually counting words.

6. No paragraphs

A full essay written as one giant paragraph tells the examiner you don't know how to organise ideas. Even with good sentences, the mark drops.

Fix: Every essay gets at least three paragraphs — introduction, body, conclusion. The body usually splits into two or three. Leave a blank line between paragraphs so the examiner can see it at a glance.

7. Spelling mistakes on words you knew in Grade 7

Because, friend, business, Wednesday, receive, government, their vs there. These are the words that come back wrong on almost every paper. Not difficult vocabulary — easy words rushed.

Fix: Keep a personal "red list" of ten words you keep getting wrong. Write each one correctly five times before every practice paper. Your list will shrink.

8. Not planning the essay

Students read the essay prompt, pick up the pen, and write the first sentence that comes to mind. Three paragraphs in, they realise they're off-topic or they've run out of ideas.

Fix: Spend two minutes planning. Write four to five bullet points in the margin of the answer booklet. Cross them out as you cover each one. Those two minutes save you ten minutes of panic.

9. Blank at the literature section

If your syllabus includes the literature texts, students lose easy marks on the contextual questions — the ones where you have to name the author, the character speaking, or the situation in the text. These marks are free if you know the basic story of each poem, prose piece and play.

Fix: Make a one-page summary for each text — title, author, main characters, one-sentence plot, one key theme. Read the summary three times a week. You don't need to re-read the full texts — you need to recognise them under pressure.

How to use the marking scheme (the right way)

The official marking schemes from the Department of Examinations are not a secret. They're published after each exam. Most students look at them once and move on. That's a waste.

Take a past paper, do it under timed conditions, then mark it yourself using the marking scheme. You'll find out two things: where you lose marks you thought you'd get, and where you earn marks you thought you'd lost. Both change how you prepare for the next paper.

Do this for four or five past papers in a row and you'll start thinking like an examiner — which is the single biggest jump a student can make in the last three months.

A realistic O/L English study week

Not a 4am start, not six hours a day. This works:

  • Monday: 30 minutes of vocabulary and grammar drill.
  • Wednesday: 30 minutes of comprehension or dialogue practice.
  • Friday: 30 minutes of writing — one letter or short composition.
  • Saturday: One full past paper, timed. Rest of the day off.
  • Sunday: Mark the paper. Note the mistakes in a book you keep for the whole year.

Two hours a week of focused, marked practice beats fifteen hours of unmarked reading.

Where Woodberry Place fits

Woodberry Place doesn't run O/L or A/L exam classes. What it does run, in Matara, is a six-month Spoken English & Grammar course at B2 level for teens aged 15 and over and adults. It covers pronunciation, grammar, and workplace and academic speaking, with explanations in Sinhala and English from a TEFL/TESOL-certified instructor. You can book a trial class before you commit. Strong grammar and confident spoken English support the skills exam papers test — reading carefully, writing clearly, and expressing ideas without translating in your head — but the course is a spoken English course, not exam coaching.

Frequently asked questions

How is the O/L English paper structured in Sri Lanka?

The paper is normally split across Paper I and Paper II, covering reading comprehension, vocabulary in context, grammar, letter writing, dialogue, and short and long composition. The literature component appears for students who sit it as a separate subject. Check the current Department of Examinations syllabus for the exact format in your exam year.

Is O/L English hard to score an A in?

It's not harder than any other subject, but students lose marks on small mechanical things — spelling, format, word count — more than on their actual English. Fixing those moves you from a credit pass to a distinction without needing better English.

Should I memorise essays for the O/L English paper?

No. Memorised essays almost always answer the wrong question, and examiners spot them. Instead, practise writing to a plan — you'll handle any topic that comes up.

How many past papers should I do before the O/L English exam?

Six to eight full timed papers, marked using the official marking scheme, is usually enough to see consistent improvement. More than that and you're repeating patterns rather than learning new ones.
