KALLIS' iBT TOEFL Pattern Reading 1: Explorer

This is very effective for international people.Startes from easy to hard. The second one is very recommended too.

This book makes my toefl score 79 at the first time. This book is really good. Nice context, good table of contents, proper example. Books from KALLIS is highly recommended.

good explanation, very useful examples.But I would say it's too easy. I didn't know that this book is for beginners

For the beginner level of ToEFl
