"Bestseller Readers" are illustrated, simplified readers that can be read in class or at home and have been carefully graded in terms of vocabulary, syntax, grammar and thematic content to meet the needs of students at each level. The books have been designed in such a way that students will be happy to read them because there are no signs of comprehension questions, exercises, etc. Instead, there is a simple glossary at the back of each book with an explanation in English of those words that may cause problems for some students and a separate activity book that provides students with an interesting way to understand and revise the story they are reading.
