Cheat Sheet

  1. Mastering Collocations -

    Understanding word partnerships like "make a decision" and "take a decision" helps you tackle C1 vocabulary quiz gap fills with confidence. Refer to the Cambridge University Collocation Dictionary for high-frequency pairs in context. Try grouping collocations by verbs to spot patterns instantly (e.g., make, do, take).

  2. Leveraging Word Formation -

    Exploring prefixes and suffixes such as "re-", "un-", "-ness" or "-able" can dramatically expand your word bank for an advanced English vocabulary test. Oxford University Press research shows that recognizing these affixes turns unknown words into understandable forms (e.g., "reconsider", "happiness"). Use the mnemonic "If you can see an affix, you can predict a twist!" to retain them.

  3. Using Context Clues -

    Leveraging context clues is vital when you choose the right word in a gap fill exercise; look for signal words like "however", "therefore", or "despite" to infer meaning. Journal of Pragmatics studies demonstrate that discourse markers guide you toward the intended lexical choice. Practice by underlining these markers as you read sample passages.

  4. Navigating Register and Nuance -

    Distinguishing formal and informal register ensures you fill gaps appropriately in a C1 Vocabulary Test - "commence" works in academic texts, while "start" suits casual dialogue. The British Council's guidelines highlight the importance of tone in advanced writing and speaking. Create a two-column chart labeling synonyms by formality for quick recall.

  5. Conquering Phrasal Verbs -

    Phrasal verbs like "put off" (postpone) or "run into" (encounter) can stump even seasoned learners in gap fill vocabulary practice. Research from the University of Leicester shows that memorizing phrasal verbs in thematic groups (e.g., time, movement) boosts retention. Use flashcards with example sentences, such as "I had to put off the meeting until Monday."
