As an IELTS candidate in the past and an IELTS book author and teacher now, I regularly visit many IELTS websites to look for revision materials. In this article, I would like to give you a list of useful and reliable IELTS websites for your revision.
Of course, my website - ieltswithmrduc.com - is one of them. However, by visiting different websites, you will be able to access different tips, advice and perspectives on how to best improve your IELTS score. All the websites that I suggest below have free and updated IELTS materials.
1. IELTS Exam Preparation: https://www.ielts-exam.net/
2. IELTS Liz: http://ieltsliz.com/
3. IELTS Advantage: https://www.ieltsadvantage.com/
4. IELTS Materials and Resources: http://ieltsmaterial.com/
5. IELTS Buddy: http://www.ieltsbuddy.com/
I believe you do not want to spend too much time going to many websites to seek IELTS revision materials. Therefore I think 5 websites should be enough for you.
