OGET (OK174) cheat sheet

Listening items test comprehension of main idea, explicit detail, inference, speaker purpose, and tone; identify which skill the stem asks for before choosing an answer.

Main-idea answers must cover the whole passage; an option that is true but covers only one sentence is a detail distractor.

Inference answers require textual support: the correct option follows necessarily from stated evidence, not from outside knowledge.

Tone and attitude are signaled by word choice, intonation cues described in the prompt, and transitions such as 'however' or 'unfortunately'.

A speaker's purpose is usually expressed by an infinitive phrase: to persuade, to clarify, to request, to warn.

Distractors commonly repeat exact words from the audio while reversing the relationship (cause/effect, before/after); paraphrase plus correct logic marks the answer.

When two speakers disagree, the tested point is often the resolution or the reason for disagreement, not either speaker's opening statement.

Numbers, dates, and names are tested as exact details; note qualifiers such as 'approximately', 'except', and 'not until'.

Reading items fall into main idea, supporting detail, inference, vocabulary in context, author's purpose, and organization/structure.

Main-idea answers are broad enough to cover all paragraphs and specific enough to exclude material the passage does not discuss.

Vocabulary-in-context: substitute each option into the sentence and keep the one that preserves the passage's logic, not the most common dictionary sense.

Inference must be a necessary conclusion; an option that is merely plausible or likely is wrong unless the text forces it.

Author's purpose is stated as a verb phrase (to explain, to compare, to criticize); tone is an adjective (sarcastic, neutral, cautious).

Signal words map to structure: 'however/but' = contrast, 'therefore/thus' = conclusion, 'for example' = illustration, 'first/then' = sequence.

Except/not questions: three options are supported by the passage and the odd one out is the answer; verify each against a specific line.

A pronoun or 'this' referring back to a prior clause is tested by locating the nearest grammatically compatible antecedent.

Multiple-choice revision items test clarity, conciseness, sentence combining, transitions, agreement, punctuation, and placement of modifiers.

Conciseness rule: prefer the shortest option that preserves meaning; redundancy such as 'return back' or 'past history' is always wrong.

A modifier must sit next to the word it describes; a sentence beginning with a participial phrase requires the subject to be the actor.

Subject-verb agreement is decided by the true subject, ignoring prepositional phrases between subject and verb.

Comma splice = two independent clauses joined by a comma alone; fix with a period, semicolon, or coordinating conjunction.

Transitions must match logic: 'however' for contrast, 'therefore' for result, 'for instance' for example, 'meanwhile' for simultaneity.

Pronoun reference is ambiguous when two preceding nouns could be the antecedent; the correct revision names the noun.

Parallel structure: items in a list or comparison must share grammatical form (all infinitives, all gerunds, all noun phrases).

Constructed-response speaking is scored on topic development, delivery (fluency, pronunciation, intonation), and language use (grammar, vocabulary).

A complete response states a position, supports it with one or two specific reasons or examples, and closes with a brief wrap-up.

Fillers ('um', long pauses) count against fluency; a short silent pause is preferable to a vocalized filler.

Intonation carries meaning: rising for yes/no questions, falling for statements and wh-questions, stress on contrastive words.

Minimal pairs and final consonants (e.g., -s, -ed, -t/-d) are frequent pronunciation targets; word-final voicing changes meaning.

Time management: spend roughly the first few seconds planning, the middle developing, and the last seconds concluding; an unfinished response loses points.

Grammar accuracy matters more than complexity; a correctly formed simple sentence outscores a broken complex one.

Content should stay on the prompt; off-topic fluency earns no credit for topic development.
