Cambridge IGCSE™ Enterprise Coursebook (Cambridge International IGCSE)

This is a miniature version of all the other cambridge university text books. The description says 198 pages... it is only 189 pages. Is it enough for IGCSE standard 9th and 10th??? I am not sure. Every other textbook seems to have so much more content. And the cost is almost Rs. 1800 (that's about 24 USD). Ridiculous. I can think of other ways the student community can be cheated.
