Using a wide range of vocabulary during the speaking cue card task can significantly boost your score. Here’s how to improve your lexical resource:

• Learn Topic-Specific Vocabulary: Prepare vocabulary related to common cue card topics, such as travel, education, and technology. This will help you express yourself more accurately.
• Avoid Repetition: Try not to repeat the same words or phrases. Use synonyms or related terms to show variety.
• Use Idiomatic Expressions: Phrases like "over the moon" or "a blessing in disguise" can help demonstrate advanced vocabulary, but use them naturally and sparingly.
• Practice Collocations: Common word pairings like "make a decision" or "take responsibility" can enhance the fluency and accuracy of your speech.
