TOEFL iBT Reading common mistakes
TOEFL iBT Reading · Understand the traps and how to avoid them.
Filling a blank with a word whose meaning fits but whose letters do not match the letter pattern shown (for example, writing a longer word where only four blanks follow the given stem, or ignoring an already-printed final letter).
Candidates read the sentence for meaning and then type the first plausible word that comes to mind, treating the printed letters as decoration rather than as a hard constraint.
What to do instead
Before typing, count the blanks and copy the printed letters onto scratch paper; after typing, compare letter by letter with the pattern. If the word does not fit the pattern exactly, discard it and generate another candidate with the same meaning.
Choosing a word that fits the topic but breaks the grammar of the sentence, such as inserting a base-form verb after a modal, a singular noun after 'several', or an adjective where an adverb is required.
Attention is fixed on meaning, so agreement, tense, and part-of-speech signals in the surrounding words are never checked.
What to do instead
Identify the part of speech the blank requires from the words immediately before and after it, then re-read the completed sentence silently once to confirm the form is grammatical.
Deciding on a word from the first two or three letters alone, without reading to the end of the sentence or glancing at the neighbouring sentence.
Many common stems are ambiguous (a stem beginning 're-' could complete as reduce, remain, or require), so the first completion that surfaces is often the wrong one, and time pressure discourages further reading.
What to do instead
Read the entire sentence plus the sentence before it before generating any candidate, and require the chosen word to satisfy both the local grammar and the broader idea of the paragraph.
Answering questions about a notice, email, or schedule from real-world expectations rather than from the specific details printed in the text (for example, assuming a standard return window or a typical opening time).
Daily-life texts feel familiar, so the brain supplies a plausible default and the candidate never returns to the text to verify the actual figure or condition.
What to do instead
Treat every question as a lookup task: find and underline the exact line containing the number, date, or condition, and reject any option that is not traceable to that line.
Misreading the scope of a question that contains a negative or an exception, such as 'Which of the following is NOT mentioned?' or 'All of the following are included EXCEPT', and then selecting the first option that is true according to the text.
Under time pressure the capitalized negative is skimmed past, and the habit of hunting for a true statement takes over.
What to do instead
Circle the word NOT or EXCEPT on the screen or scratch paper before reading the options, then test each option against the text and mark the three that are supported before choosing the leftover one.
Judging the purpose or tone of a short text as neutral information when it is actually promotional, persuasive, or a complaint, and then choosing an answer about content instead of intent.
Candidates read for facts only and skip the framing elements - sender, recipient, subject line, and evaluative adjectives - that reveal why the text was written.
What to do instead
Before answering, state in one sentence who wrote the text, to whom, and what they want the reader to do; use that statement to eliminate any option that misidentifies the goal.
Selecting an answer option because it repeats a word or phrase from the passage, without checking whether the rest of the option matches what the passage actually says.
Lexical overlap feels like confirmation, and distractors are deliberately built by lifting vocabulary from the text while reversing or exaggerating the relationship.
What to do instead
For each tempting option, locate the corresponding passage sentence and confirm that every element of the option - subject, verb, direction, and degree - is stated or implied there. Reject options supported only by a shared keyword.
Choosing an option that is factually true in the real world but not stated or implied in the passage.
Background knowledge on familiar science or history topics fills gaps automatically, and the resulting inference feels like something the passage said.
What to do instead
Adopt the rule that an answer is correct only if you can point to the sentence that licenses it. If the justification is 'everyone knows that', eliminate the option.
Answering a rhetorical-purpose question ('Why does the author mention X?') with a restatement of the sentence's content rather than a description of the job that sentence performs in the argument.
Content restatements are easy to recognize and feel safe, while purpose requires relating the sentence to the claim before or after it.
What to do instead
Read the target sentence together with the sentence that precedes and follows it, then phrase the answer to yourself as a verb phrase such as 'to provide an example of', 'to concede a point', or 'to introduce a contrast', and match that to an option.
Treating inference items as licence to speculate, choosing an option that goes several logical steps beyond the passage instead of the minimal step the text supports.
The word 'infer' is read as 'guess', and highly specific or dramatic options feel more like real conclusions than modest ones.
What to do instead
Require the correct inference to follow in one step from stated evidence, and prefer the most conservative option that the evidence forces; discard any option that needs an extra assumption the passage never supplies.
