Query: Not enough to pass the OCP exam.

This book does not cover the exam topic completely. The second part is nothing. This book could be a good introducing book on Internet application form building, but absolutely not for OCP preparation. This book gave not enough example to build Oracle forms with not clear explanation on important concepts, and usages. Persons get OCP only by this book actually does not learn some of Oracle.
