Key Concepts Breakdown
1 High-Frequency SAT Words
The SAT tests a core set of vocabulary words that appear repeatedly across reading passages and writing questions. Students must know precise definitions and understand how words function in context, since SAT questions rarely ask for definitions directly but instead test meaning within a sentence or passage. Words often have multiple meanings, so understanding connotation and part of speech is critical.
Key Points
- Focus on Tier 2 academic words: words used across disciplines (e.g., ambiguous, corroborate, mitigate, pragmatic)
- SAT tests words in context — the correct answer fits the tone and logic of the surrounding sentence
- Watch for words with positive/negative connotations: 'tenacious' (positive persistence) vs. 'obstinate' (negative stubbornness)
- Common high-frequency SAT words include: advocate, benign, candid, dubious, elusive, fervent, lucid, malleable, novel, peripheral, scrutinize, vacuous
In the passage, the scientist's findings were described as _______ because they contradicted decades of accepted research. (A) corroborated (B) anomalous (C) pragmatic (D) benign
The sentence signals that the findings went against established knowledge, so the blank needs a word meaning 'out of the ordinary' or 'unexpected.' 'Anomalous' means deviating from what is standard or expected, which matches perfectly. 'Corroborated' means confirmed, 'pragmatic' means practical, and 'benign' means harmless — none fit the context of contradicting accepted research.
2 ACT Vocabulary
The ACT tests vocabulary less directly than the SAT but still requires students to identify the most precise word choice in context through the English section's 'Word Choice' questions. Students must distinguish between words that are close in meaning but differ in precision, formality, or connotation. The ACT also tests commonly confused words (affect/effect, than/then, lay/lie) and redundant word pairs.
Key Points
- ACT Word Choice questions ask which option is most precise, concise, or appropriate for the passage's tone
- Eliminate answers that are redundant (e.g., 'past history' — 'past' is redundant with 'history')
- Know commonly confused pairs: affect (verb) vs. effect (noun), imply (speaker) vs. infer (listener), fewer (countable) vs. less (uncountable)
- Formal vs. informal register matters: academic passages require formal word choices; colloquial options are usually wrong
The committee's decision had a profound _______ on the school's budget for the following year. (A) affect (B) effect (C) impact on (D) influence upon
The blank follows the article 'a' and functions as a noun in the sentence, so 'effect' (noun) is correct, not 'affect' (typically a verb). Options C and D are grammatically awkward because 'had an impact on on' and 'had an influence upon on' create redundancy with the preposition already in the sentence. 'Effect' alone is the most precise and concise choice.
3 Test-Taking Strategies
When students do not know a word's meaning, structural clues within the word itself and context clues within the sentence can eliminate wrong answers and identify correct ones. Students should use prefixes, roots, and suffixes to decode unfamiliar words, and use the tone and logic of the surrounding text to narrow choices. Avoiding 'trap' answers — options that sound related to the topic but do not fit the sentence logic — is essential.
Key Points
- Use root knowledge to decode words: 'bene-' = good (benevolent, beneficial), 'mal-' = bad (malevolent, malign), 'circum-' = around (circumvent, circumspect)
- Context clues: look for contrast signals (but, however, although) which indicate the blank should be opposite in meaning to nearby words
- Continuation signals (moreover, similarly, in addition) indicate the blank should match the tone or meaning of nearby words
- Eliminate answers based on connotation first — if the passage is positive in tone, eliminate negatively-charged words regardless of meaning fit
Despite her _______ attitude toward failure, Maya continued to submit her work to publishers, refusing to give up after dozens of rejections. (A) resilient (B) sanguine (C) despondent (D) indifferent
The signal word 'despite' introduces a contrast, meaning the blank must contrast with 'refusing to give up' — so a negative or contradictory attitude is implied. 'Despondent' (deeply sad or hopeless) creates the contrast: despite feeling hopeless, she kept going. 'Resilient' and 'sanguine' (optimistic) would not contrast with perseverance, and 'indifferent' (uncaring) does not match the emotional weight the sentence implies.
