European Baccalaureate Other National Language (ONL) common mistakes

European Baccalaureate Other National Language (ONL) · Understand the traps and how to avoid them.

Mistake 1

In the ONL Language 1 written paper, the candidate answers the comprehension questions by lifting whole sentences verbatim from the source text instead of reformulating them in their own words.

Under time pressure, copying feels safer than paraphrasing, and candidates trained on short-answer tests assume quotation is acceptable. They also fear that rewording will distort the author's meaning, so they hedge by copying. This is penalised because the comprehension section tests whether the candidate has understood and can restate the content, not whether they can locate it.

What to do instead

Before the exam, practise a three-step routine on past-style passages: locate the relevant lines, close the text, write the answer from memory in one sentence, then reopen the text only to check facts. Train the habit of changing structure (active to passive, clause to noun phrase) and vocabulary while preserving meaning. In the exam, reserve two minutes at the end of the comprehension section to reread each answer and strike any phrase of four or more words that appears identically in the source unless it is a technical term or a quoted expression the question explicitly asks for.

Mistake 2

In the Language 1 essay or commentary, the candidate produces a competent but generic essay that never engages with the specific wording of the prompt, ignoring the genre, register, or task type demanded (for example, writing a discursive essay when an informal letter or a speech was requested).

Candidates rehearse one essay template and apply it to every task, because templates feel efficient under exam pressure. They also skim the prompt for a topic keyword and start planning before reading the full instruction, missing constraints such as audience, length, or required text type. The result is a response that is linguistically sound but off-task, which caps the mark in the task-fulfilment criterion.

What to do instead

Adopt a fixed prompt-decoding step: underline the topic, the text type, the audience, the register, and any required content points before writing anything. Build a small mental checklist of conventions for each text type likely to appear (formal letter, article, speech, review, narrative) and practise producing each in 35 to 40 minutes. In the exam, write a one-line task statement at the top of the plan and check the finished text against it before submitting.

Mistake 3

In the Language 1 oral examination, the candidate delivers a memorised monologue on the prepared topic, then collapses when the examiner asks a follow-up question, answering in single words or reverting to a different language.

Candidates prepare written answers and learn them by heart because that feels like control. Memorised speech is delivered fluently but does not build the interactive and spontaneous skills the oral tests, and it leaves no reserve of vocabulary for unscripted questions. Anxiety then triggers a fallback to the stronger language.

What to do instead

Prepare topics as bullet-point idea maps rather than scripts, and rehearse speaking from the bullets aloud with a timer and a partner who asks unpredictable questions. Practise repair strategies explicitly: asking for clarification, paraphrasing around a missing word, and buying time with natural fillers. Record yourself and listen for the moment you switch languages, then rehearse a standard self-correction phrase to return to the target language.

Mistake 4

In the Language 2 written paper, the candidate writes a structurally correct text but makes systematic errors that a stronger candidate would have eliminated: wrong gender and agreement, incorrect case or preposition government, and verb forms chosen by feel rather than by rule.

Language 2 learners often have strong receptive skills and weak productive control, so they read their own writing as correct because it sounds right. They also prioritise content over accuracy in practice, never building an error log, so the same high-frequency mistakes recur across papers.

What to do instead

Keep a personal error log categorised by type (gender, agreement, tense, preposition, word order) and review it before each practice paper. Learn nouns with their article and plural from the start, and drill the five or six structures that generate most of your errors until they are automatic. In the exam, allocate a dedicated final five to eight minutes for a targeted proofread of exactly those categories rather than a general reread.

Mistake 5

In the Language 2 oral, the candidate treats the task as a memory test on a prepared text, gives a summary rather than a reaction, and cannot sustain a two-way exchange or defend an opinion when challenged.

The oral is often prepared in class with a fixed text, so candidates assume the examiner wants recall. They also lack practice in expressing opinion, concession, and disagreement in the target language, so when asked 'why do you think that?' they run out of language and fall silent.

What to do instead

Prepare each topic with three layers: a factual summary in five sentences, two personal opinions with reasons, and one counter-argument you can rebut. Learn a small repertoire of discourse markers for opinion, concession, and exemplification, and rehearse them until they are automatic. Practise with a partner who deliberately disagrees with you so that defending a position becomes routine rather than a surprise.

Mistake 6

In the Mathematics written examination, the candidate loses marks not on method but on presentation: no working shown, units omitted, answers unrounded as instructed, or a final result stated without justification.

Candidates who can do the calculation mentally skip the written steps because they see them as redundant, and they treat the answer as the only thing being marked. They also misread instructions about rounding, significant figures, or exact versus decimal form, and they run out of time before checking units.

What to do instead

Work to a fixed layout for every problem: state the formula or method, substitute, compute, then state the answer with units and the required precision on a separate final line. Practise under timed conditions so that showing working becomes automatic rather than a luxury. Before the exam, list the precision conventions your specification uses and apply them deliberately in the last five minutes of checking.

Mistake 7

In Mathematics, the candidate misreads the question and answers a different problem: solving for x when asked for an expression, finding a probability when asked for odds, or ignoring a condition such as 'given that' or 'exact value'.

Under time pressure, candidates pattern-match the opening words of a question to a familiar exercise type and start calculating before reading to the end. Multi-part questions worsen this, because the candidate carries an assumption from part (a) into part (b) without noticing that the conditions changed.

What to do instead

Adopt a read-twice rule: first read for the topic, second read with a pen underlining what is asked, the given conditions, and the required form of the answer. After solving, restate the question in one line and check that your answer matches it. For multi-part questions, re-read the stem at the start of each part, since conditions often change.

Mistake 8

In the History or Geography oral taught through Language 2, the candidate presents accurate content but relies on a memorised script, cannot handle a document or map placed in front of them, and answers follow-up questions in fragmentary sentences with weak subject-specific vocabulary.

The subject is assessed orally in a second language, so candidates over-invest in memorising content and under-invest in the language of analysis. They have rarely practised interpreting an unseen source aloud, and they lack the connective vocabulary (cause, consequence, continuity, change, bias, scale) needed to structure an argument in real time.

What to do instead

Practise with unseen documents: give yourself five minutes to read a short source or map, then speak for three minutes identifying nature, origin, purpose, and limits, and linking it to the wider topic. Build a glossary of analytical expressions in the target language for cause, consequence, comparison, and evaluation, and use them in every practice answer. Rehearse a structure for the follow-up: direct answer, evidence, explanation, link back to the question.

Mistake 9

In the History or Geography oral, the candidate describes the document or narrates events without answering the question, and never evaluates the source's reliability or provenance.

Description feels safe and fills time, and candidates equate knowing the content with answering the question. Source evaluation is often taught late or superficially, so candidates mention origin without explaining how it shapes what the source can and cannot show.

What to do instead

Use a fixed oral frame: identify the document, state its main idea in one sentence, explain two things it reveals, explain one limit or bias, then answer the question directly. Practise on sources with clear provenance (a propaganda poster, a colonial map, a ministerial speech) so the link between origin and interpretation becomes habitual. Always end with an explicit sentence beginning 'Therefore, this document shows that...'.

Mistake 10

Across the optional and complementary subjects (additional ONL, sciences, philosophy, economics), the candidate misjudges the assessment format: preparing only for the written component when an oral exists, or treating an optional subject as low-stakes and under-preparing relative to its weighting.

Optional subjects are often chosen for interest or timetable reasons, and candidates assume they will be assessed like their main subjects. They may not have read the specific assessment description, so they prepare essays when the paper is short-answer, or neglect the oral entirely. Because these subjects feel peripheral, revision time is squeezed by compulsory subjects.

What to do instead

Obtain the official assessment description for each optional subject at the start of the year and map every component (written, oral, practical, coursework) with its weighting and format. Build a revision plan that allocates time in proportion to weighting, not to interest, and schedule at least two full mock assessments per component. For any oral component, rehearse aloud from the first month rather than in the final weeks.
