On the first page of the book there is a description of ‘the class’ and ‘the teacher’. It was obviously written to attract any reader. But I found the description somewhat misleading. The description of ‘the class’ can be stated as grossly wrong. And if I were the author, I would feel hurt about such descriptions.
The publisher should have taken care of that. However much one would like to spice it up it must not be ‘wrong’.
