Do you find it difficult to study as much as you would like to? Perhaps you make study plans but then decide to "do it later". This is what we call 'procrastination'.

Let me know if procrastination is a problem for you (with regard to your IELTS preparation, or anything else), and we can discuss some ways to beat it.
