Why is vocabulary important for exams?
Vocabulary is key to every part of the English test. If you know enough vocabulary, you'll be able to understand questions, listen with more focus, write more varied sentences, and speak more fluently. Research has shown that people who have a vocabulary of at least 3,000-4,000 words tend to score higher on tests because they don't waste time guessing meaning during the test. So memorizing vocabulary isn't boring, but rather an investment that can help you get closer to your target score faster.
