My favorite site for working with preschool students. I am currently working as a teacher in China, and my main audience is children.

Earlier I mentioned the Britishcouncil site as the main resource for preparing for international exams like IELTS, and while researching the Internet for exam preparation, I came across the site of the wonderful Liz. Her site focuses specifically on preparing for IELTS, it's perfectly and very simply structured, with all the main difficult parts of the exam sorted out in a nutshell. Definitely, it is a worthwhile site.

All so-called readers are categorized according to levels in the international classification.
