5 tips to improve English vocabulary to achieve a high IELTS band score

Building a strong vocabulary is a key challenge for many IELTS candidates. Since a limited vocabulary can hinder performance in all four sections of the exam, expanding your word bank is essential. However, mastering new words is not an overnight process; it requires consistent effort and effective strategies. To support your IELTS preparation, PREP introduces five simple yet powerful techniques to improve English vocabulary and maximize your chances of achieving a high band score.

I. How to improve English vocabulary for the IELTS test

Before diving into vocabulary learning techniques, it is important to recognize how vocabulary is interconnected with grammar and pronunciation. A well-rounded approach to learning words should include understanding their grammatical usage and correct pronunciation. To get started, create a structured study plan that integrates vocabulary with these essential components.
A useful first step is to set up a dedicated vocabulary notebook. Keep it organized and visually appealing to make the learning process more engaging. Choosing the right study materials is equally important. Consider using:

• Textbooks and printed materials: Hard copies of IELTS preparation books and newspapers provide valuable exposure to new words.
• Online resources: Websites, YouTube tutorials, and vocabulary-building platforms offer free and interactive learning opportunities.
• Dictionaries: Both online and print dictionaries, such as Cambridge, Collins, and Oxford, are indispensable for learning word meanings, usage, and pronunciation.

II. 5 Effective Tips to improve English vocabulary

To improve English vocabulary requires not only memorization but also the ability to use words flexibly, particularly in the IELTS Speaking and Writing sections. But what is the best way to build English vocabulary effectively?  
To begin with, it is important to recognize that IELTS vocabulary is vast and consists of various word types. However, starting with simpler words is advisable, as it helps establish a strong foundation. Once you are comfortable with basic vocabulary, you can gradually expand your word bank and improve retention techniques.  
Moreover, learning vocabulary is not just about remembering individual words. Instead, you should also study related words to form a well-connected network of vocabulary. Organizing words systematically rather than memorizing them in isolation will make it easier to recall and use them appropriately.

1. Improve English vocabulary by neatly writing words in a notebook

A useful way to improve English vocabulary is by keeping a well-organized vocabulary notebook. Instead of simply noting down words randomly, it is more effective to categorize them by topic. This approach not only helps you systematically expand your vocabulary across different subject areas but also makes revision easier.  
For instance, I aim to learn around eight new words each day, though it’s important to adjust the number based on individual capacity to avoid feeling overwhelmed, which could hinder progress. In my notebook, I record each word along with its meaning and pronunciation. I usually select words from high-scoring Writing or Speaking samples and include an example sentence, emphasizing key phrases that feature the target word. This structured method enhances both memorization and application.

2. Review vocabulary after 1 day, 1 week, and 1 month

To effectively expand vocabulary, it is essential to establish a habit of regular review. A proven method is to revisit new words after one day, one week, and one month. Even if you don’t have time to spell out each word as you might have done in school, simply rereading them can reinforce retention.  
By consistently reviewing your vocabulary, you maximize the benefits of your well-organized notebook and strengthen long-term memory. The more frequently you encounter a word, the more naturally it will become part of your active vocabulary. Start applying this strategy today to improve your ability to recall and use IELTS vocabulary with confidence!

3. Improve English vocabulary through playing Crosswords or Wordsearches

A fun and interactive way to enhance English vocabulary is by incorporating word games like crosswords and word searches into your study routine. These activities allow you to “learn while playing and play while learning,” making vocabulary acquisition more engaging and effective.
You can try this method with a study partner by creating your own word puzzles using online tools such as Crossword Labs or The Word Search. If you prefer ready-made puzzles, Word Search 365 offers topic-based word searches, covering categories like Food and Animals, with varying difficulty levels. This enjoyable approach not only makes learning more dynamic but also helps reinforce vocabulary more effectively than passive reading alone.

4. Use e-flashcards to improve your IELTS vocabulary

Using flashcards is a well-known technique for learning IELTS vocabulary, but traditional paper flashcards can be time-consuming and inconvenient, especially for busy individuals. A more efficient alternative is to create digital flashcards using Quizlet, one of the most popular learning apps available today.  
With Quizlet, you simply enter a list of words along with their meanings, and the app automatically generates flashcards for you. This allows for quick and convenient review anytime—whether you're waiting for a bus or an elevator. Additionally, you can share your word lists with a study partner, making it easier to reinforce vocabulary together. This digital approach enhances both flexibility and efficiency in vocabulary learning.

5. Learn additional synonymous vocabulary for IELTS

To further expand your vocabulary, it is essential to learn synonyms of the words you already know. Synonyms frequently appear in the IELTS exam, so paying close attention to them can be highly beneficial.
Additionally, incorporating synonyms into your Speaking and Writing tasks allows you to express ideas more precisely and avoid repetition, which can help improve your score. By practicing the flexible use of synonyms, you can demonstrate a wider range of vocabulary and enhance the overall quality of your responses.
