TOEFL iBT common mistakes
TOEFL iBT · Understand the traps and how to avoid them.
Answering Reading questions from memory or general knowledge after skimming the passage once, without going back to locate the sentence that proves the choice.
Under time pressure, candidates trust a global impression of the passage (and their own background knowledge of the topic), so they pick options that 'sound right' rather than options the text supports.
What to do instead
For every question, physically point to the line(s) in the passage that justify the answer before selecting. If you cannot find a supporting sentence, the option is wrong even if it is factually true. Train by writing the paragraph number next to each answer you choose.
Spending 25+ minutes on the first passage, then rushing or guessing on the last one.
Early questions feel solvable and candidates refuse to abandon them, and there is no visible per-question clock discipline.
What to do instead
Budget 18 minutes per passage and keep 2 minutes as buffer. If a question is still unresolved after ~90 seconds, mark it, choose the best remaining option, and move on. Practise full 3-passage sets with a visible timer so the pacing becomes automatic.
Misreading the question stem - treating an inference, rhetorical-purpose, or EXCEPT question like a simple fact question, or overlooking 'NOT'/'EXCEPT' and picking three true statements instead of the false one.
Candidates read stems quickly and pattern-match to a familiar question type; negative and inference stems look almost identical to detail stems at a glance.
What to do instead
Underline the key operator in every stem (infer / why does the author mention / EXCEPT / according to the passage) before looking at options. For EXCEPT questions, label each option T or F against the passage and select the odd one out. For inference items, reject any option that is stated outright rather than implied.
Trying to transcribe the audio word-for-word, so the notes are two or three lines behind and the next main point is missed entirely.
Candidates fear forgetting details and equate more notes with better comprehension, but writing full sentences consumes working memory needed for listening.
What to do instead
Note only the lecture's frame: main topic, 2–4 supporting points, one example per point. Use abbreviations, symbols and arrows (→ for cause, ≠ for contrast), and write nothing during the first 20 seconds while you identify the topic. Practise by pausing a 5-minute lecture and summarising your notes aloud - if the summary is impossible, the notes were too detailed.
Selecting an option because its content was mentioned in the audio, even when the question asks about the speaker's purpose, attitude, or what is implied.
Recognising a phrase creates a feeling of correctness; candidates stop analysing once they hear a familiar keyword.
What to do instead
Before choosing, restate the question to yourself in plain words ('Why does she say this?' / 'How does he feel about X?'). Then check whether the option answers that question, not whether it was mentioned. Pay attention to intonation, hedges ('well, it might…'), and contrast markers ('but', 'the real problem is') to catch attitude and implication.
Delivering a memorised template answer that only loosely fits the prompt, then running out of time before giving a specific reason or example.
Templates reduce anxiety and feel fluent, so candidates force the prompt into the template instead of answering the actual question; rehearsed openers also eat 10–15 of the 45 seconds.
What to do instead
Use prep time to write three keywords that answer the exact question, and make your first sentence name the topic directly. Structure: direct answer → one reason → one concrete detail (person, place, number, or short past event). Record yourself and check that a listener could identify the question from your answer alone.
Speaking too fast or too quietly into the microphone, swallowing word endings, and never listening back to recordings.
Nervousness speeds up delivery and drops volume; without playback, candidates cannot hear their own unclear segments or repeated fillers.
What to do instead
Record every practice response and transcribe 30 seconds of it verbatim - mark dropped endings, repeated 'um/like', and unclear words. Aim for a steady, slightly slower pace with clear consonants and brief pauses at commas instead of filling gaps with sound. Practise at the same volume and mic distance you will use on test day.
In Integrated Writing, summarising the lecture as a stand-alone list and copying phrases from the reading passage without linking each lecture point to the reading point it challenges.
Candidates treat the task as two summaries and borrow the reading's wording because it is already in front of them, which the task penalises.
What to do instead
Take notes in a three-row table: reading claim | lecture counter-claim | detail/example. Write one body paragraph per row, opening with 'The lecturer challenges the claim that…' and paraphrasing both sources in your own words. Target 150–225 words in 20 minutes and reserve 3 minutes to check that every lecture point is explicitly connected to a reading point.
In the Writing for an Academic Discussion task, writing a full five-paragraph essay with a general introduction and conclusion, and never referring to the other students' posts.
Candidates transfer the essay formula learned for longer academic writing tasks and use the first 100+ words setting up context instead of contributing to the discussion.
What to do instead
Skip the introduction and conclusion. Spend the first sentence stating a clear position, then add two or three sentences of reasoning plus one specific example, and explicitly engage one classmate ('Although Kim argues X, the evidence suggests Y'). Aim for 120–180 words in the 10-minute window, editing for grammar in the final 90 seconds.
Submitting Writing responses without proofreading, leaving repeated subject–verb agreement, article, and spelling errors, and falling under the required word count.
The clock creates a 'finished is better than polished' reflex, and candidates do not know their own habitual error patterns, so they cannot scan for them efficiently.
What to do instead
Keep a personal list of your top five recurring errors found in marked practice essays and do a targeted 2-minute scan for only those items. Learn your word-count pace from timed practice (count words on screen) so you finish with editing time to spare, and use the on-screen counter to confirm you are above the minimum before submitting.
