The 5 highest-impact mistakes at a glance
- Flattening 第四声 (4th tone) — especially on 是. The single most common Singapore tone error.
- One-line conversation answers with no PEEL structure. The biggest gap between AL1 and AL3.
- Memorised template answers that fail when examiners probe with 你同意吗 or 哪一个最有用.
- Code-switching to English on words the child knows in Chinese — 因为, 例如, 朋友.
- Missing connectors. Three sentences with no 因为/所以/例如 reads as P3-level vocabulary.
SEAB does not publish exam-error data, so this list is not an official ranking. It is built from nine years of public PSLE Chinese Oral exam patterns (2017–2025), post-exam parent reports, and analyses published by Singapore tuition centres on the gap between AL1 and AL3 students. Every mistake on the list is Singapore-specific — these are not generic Mandarin learner errors. A student in China would not make most of them; a student in Singapore is at risk of all ten.
The pattern that shows up across cohort after cohort: AL3 students rarely fail at one mistake catastrophically. They lose two or three marks here, two or three there, across five or six of the mistakes below — and the small leaks compound. Fixing three of these in six weeks of focused practice is what shifts an AL3 to an AL2.
Mistake 1. Flattening 第四声 (4th tone) — especially on 是
The 4th tone (shì) is a sharp downward fall — not a flat, neutral sound. Singapore students consistently flatten it, especially on 是 (shì), which appears in almost every passage and conversation answer. The character gets read as a 1st tone (shī) or a soft non-tone (shi), and an examiner hears the slip every few sentences across the entire reading.
Why it costs marks: pronunciation (语音) is one of the four scored dimensions in reading aloud. 是 is so high-frequency that getting it consistently wrong drags the pronunciation score by itself. Worse, the slip carries into conversation, where 我觉得是…(“I think it is…”) is a default opener that gets repeated every answer.
The fix
Drill 是 in isolation, exaggerating the downward fall — start high, drop sharply. Then drill three short sentences: 这是我的书。她是我的朋友。今天是星期一。 Once the 4th tone on 是 locks in, other 4th-tone characters (不、要、对) usually follow within a week.
Mistake 2. Confusing 第二声 and 第三声 (rising vs dipping)
The 2nd tone is a clean upward rise (má); the 3rd tone is a dip — down then up (mǎ). Singapore students routinely produce both as a vague mid-rise that is neither. The classic minimal pair is 买 (mǎi, “to buy”) vs 卖 (mài, “to sell”) — though the more dangerous confusion is between 2nd and 3rd, since they are actually closer in pitch contour than 3rd and 4th.
Why it costs marks: tone errors compound. A passage with five 2nd/3rd-tone confusions will already tip pronunciation into mid-band. The examiner does not need to flag every single one — three or four are enough to register the pattern.
The fix
Practise the four-tone drill on a single syllable until each tone is distinct: 妈 mā 麻 má 马 mǎ 骂 mà. Have the child exaggerate the dip on the 3rd tone — over-correction is fine in practice; it normalises in performance.
Mistake 3. No tone sandhi on 一
一 is read 1st tone in isolation (yī) — but in context, the tone shifts. Before a 4th-tone syllable it becomes 2nd tone: 一个 (yí ge). Before a 1st, 2nd, or 3rd-tone syllable it becomes 4th tone: 一天 (yì tiān), 一年 (yì nián), 一起 (yì qǐ). Singapore students almost universally read 一 as a flat 1st tone in every position.
Why it costs marks: 一 is one of the highest-frequency characters in any passage. A failure to apply tone sandhi means the examiner hears the same wrong tone 8–10 times per passage. It also signals that the student has not built the listening reflex underneath the reading — a marker of register more than a marker of effort.
The fix
Memorise three pairs: 一个 (yí ge), 一天 (yì tiān), 一起 (yì qǐ). Repeat each pair 10 times daily for a week. Once the three patterns are reflexive, every 一 in any passage gets the correct tone automatically.
Mistake 4. 多音字 errors on 得 / 的 / 地
The three classic 多音字 — 得、的、地 — appear in almost every PSLE reading passage, often multiple times. Each has two or three correct readings depending on grammatical role. 得 is read de after a verb (跑得快), děi when it means “must” (我得走了), and dé in compounds (得到). Most students default to one reading and apply it everywhere.
Why it costs marks: every 多音字 error is a pronunciation error under the rubric. Three errors on these three characters in a single passage is enough to drop pronunciation by a full band. For the full list of high-frequency PSLE 多音字 with paired example phrases, see the top 10 多音字 guide.
Mistake 5. Reading every passage in the same flat news-reader voice
Reading aloud is scored on expression (语感) — not just on tones and accuracy. A child who reads a story about a child helping their grandfather in the same flat voice they would use for a school announcement is leaving expression marks on the table. Examiners want to hear the sentence mood: questions rise, exclamations carry energy, reflective passages slow.
Why it costs marks: expression is roughly a quarter of the 20-mark reading score. Flat reading caps expression at mid-band even when pronunciation is clean — and that alone can be the difference between AL2 and AL3 on the reading component.
The fix
Have your child read the same passage twice. First reading: as a news announcer reading a public notice. Second reading: as a parent reading a bedtime story. The two reads should sound clearly different. If they sound identical, the expression skill has not yet developed — and the daily reading routine should add 2 minutes of “same passage, two voices” until it does.
Mistake 6. One-line conversation answers — no PEEL structure
The single biggest gap between AL1 and AL3 students on the conversation component is not Chinese proficiency. It is answer depth. A child who answers 我觉得很好(“I think it's good”) and stops is giving an AL3 answer even when their pronunciation is perfect. The PEEL framework — Point, Explain, Example, Link — is the structural fix that AL1 students apply almost reflexively.
Why it costs marks: content depth (内容充实) is one of four conversation dimensions. A one-line answer caps that dimension at mid-band no matter how clean the Chinese is. Three short answers across Q1, Q2, Q3 cap the conversation score in the AL3 zone.
The fix
Drill PEEL in English first, then in Chinese. After any opinion the child states at home, ask three follow-ups in order: “Why do you think that?” (Explain), “Can you give me an example?” (Example), “So what does that mean?” (Link). See the PEEL framework guide for the worked Chinese versions.
Mistake 7. Memorised template answers
A child who memorises a 60-word essay on “helping others” and recites it whenever a relevant topic appears is doing exactly what examiners are now trained to defeat. Since around 2023, the 你同意吗? opinion question has dominated Q2 — and follow-up probes like 你刚才说了几个方法,你觉得哪一个最有用?(“You mentioned a few methods — which is most useful?”) are specifically designed to break a script.
Why it costs marks: a memorised answer that does not address the actual question is penalised on content. A scripted child who cannot handle the follow-up is then penalised on fluency too — long pauses, false starts, “I don't know what you're asking” signals. See why memorised answers are failing for the full breakdown.
Mistake 8. Code-switching on words the child knows in Chinese
Singapore students naturally code-switch — that is fine for “MRT”, “HDB”, and proper nouns. It is not fine for words the child has been taught in Chinese: 因为 (because), 重要 (important), 朋友 (friend), 例如 (for example), 环境 (environment), 帮助(help). When a P6 child says “because it's very important to my friends” mid-Mandarin-answer, the examiner hears a vocabulary deficit they do not actually have.
Why it costs marks: vocabulary use (词汇运用) is its own scored dimension. Three or four English insertions per answer caps vocabulary at mid-band. The child gets penalised for not deploying words they actually know — which is the most frustrating mark loss of all because it is the easiest to fix.
The fix
Run a 10-minute “Chinese-only” window at home daily — 10 minutes where every word said by the child must be in Chinese, even if the sentence breaks. Track the count of English words slipped in across the week; expect it to drop from 10+ per session to 2–3 within three weeks.
Mistake 9. Answering the wrong question
Q2 (看法, opinion) asks for the child's view. A common AL3 mistake: instead of giving an opinion, the child retells the video — describing what happened a second time. Q3 (经验, experience) asks for a personal story. A common AL3 mistake: the child gives a generic opinion instead of a specific story. The mismatch between question type and answer type is one of the most reliable AL3 markers.
Why it costs marks: an off-target answer scores low on content even when the Chinese is fluent. Examiners may follow up with a redirect (我问的是你的看法, “I'm asking for your view”) — but the redirect itself signals the child missed the question, and the answer that follows is usually rushed.
The fix
Drill question-type recognition: 看法 = opinion (start with 我觉得…); 描述 = describe (start with 在短片里…); 经验 = personal story (start with 记得有一次…). The opener tells the child which mode they should be in.
Mistake 10. Missing connectors
Three sentences in a row with no connectors — no 因为 (because), 所以 (therefore), 例如 (for example), 虽然…但是… (although…but…) — reads as P3-level Chinese, not P5–P6 register. The vocabulary may be technically correct, but the absence of connectors signals to the examiner that the child is producing isolated sentences rather than reasoned argument.
Why it costs marks: connectors are explicitly part of the vocabulary dimension. They are also what makes PEEL structurally visible to the examiner — the “Explain” and “Example” steps need 因为 and 例如 to land. A child with PEEL content but no connectors will sound less coherent than they actually are.
The fix
Memorise four connector pairs as a fixed kit: 因为…所以…, 虽然…但是…, 不但…而且…, 如果…就…. Drill one new connector every week; track usage across sessions. By week four, all four should appear naturally in conversation answers.

Most P5–P6 students show some version of three to five of these mistakes. Pick the two highest-impact ones for your child (use the diagnostic linked below if you are unsure) and drill them one at a time — not in parallel. Adding the third mistake to the drill rotation only after the first is reflexive.
Want to know which of these 10 your child is actually making? The free PSLEPrep diagnostic runs your child through one PSLE-format reading passage and one conversation video, scores against the four-dimension rubric, and flags which of these mistakes are dragging the score most.

Frequently Asked Questions
Which Chinese oral mistake costs the most marks?
For most AL3 students, mistake 6 (one-line answers / no PEEL structure) costs the most absolute marks because content depth is roughly a third of the 30 conversation marks. For students who otherwise have strong content, mistake 1 (flat 4th tone, especially on 是) is the single highest-frequency error and can drag pronunciation alone by a full band. Diagnose before drilling.
Are tone errors fixable for English-speaking households?
Mostly yes, with a feedback source. English-speaking parents cannot usually hear tone errors well enough to coach them live — but they can run the drill routine, and outsource the assessment to either a Chinese-speaking tutor or an AI-scored tool that returns per-character tone feedback. Mistakes 1, 3, and 4 (4th tone, 一 sandhi, and 多音字) are the most learnable from drill alone. Mistake 2 (2nd vs 3rd tone) needs an ear that can hear the difference — which is why diagnostic feedback matters.
Why are memorised answers now a problem?
Since around 2023, examiners have shifted toward question formats specifically designed to defeat scripts: 你同意吗? requires the child to actually take a position; follow-up probes like 你刚才说了几个方法,你觉得哪一个最有用? require the child to evaluate their own answer. A scripted child has prepared content but not thinking — and the gap shows immediately.
How many of these mistakes is normal for a P5 student?
Most P5 students show some version of four to six of these — typically 1, 6, 8, and 10 are the most common across the cohort, often with one or two of 2, 3, 4, or 5 layered on top. P5 is the right time to diagnose; P6 is the right time to drill. A child still showing seven or more of these mistakes by mid-P6 needs a more concentrated intervention than a once-a-week tuition class.
What's the fastest one of these to fix?
Mistake 7 (memorised templates) — the “fix” is immediate: stop drilling memorised essays and start drilling vocabulary banks plus PEEL structure instead. Mistake 3 (一 sandhi) is the fastest mechanical fix — three pairs memorised over one week locks in. Mistake 9 (answering the wrong question type) can flip in two weeks once the child knows which opener cues which mode.
