Frequently Asked Questions

Q: How many different trend words should I use in one response? A: Aim for 8-12 different trend-related words/phrases per response to demonstrate vocabulary range without overcomplicating your writing.

Q: Is it better to use simple or complex vocabulary? A: Use complex vocabulary accurately rather than simple vocabulary repeatedly. Accuracy is more important than complexity.

Q: Should I memorize vocabulary lists? A: Focus on understanding usage patterns and practicing in context rather than rote memorization. Contextual learning is more effective.

Q: Can I invent new trend descriptions? A: Stick to established academic vocabulary. Creativity in combinations is good, but invent new words or phrases.

Q: How do I remember all this vocabulary during the exam? A: Practice until usage becomes automatic. Focus on 30-40 core terms that you can use confidently rather than trying to remember everything.
