Oracle Certification Prep for 1z0-061: Oracle Database 12c, SQL Fundamentals Paperback – September 3, 2013

But I have not taken the exam so I can't say the info in this book provides an answer to most of the test questions. My instructor also referred me to to a website that provides 30 day online access f/69.99 for test prep. [...]

This is a good summary of 12c SQL, but I just took the test and this study guide will only get you so far. I also bought practice test software and that helped more than this guide did as far as preparing for the test. But since the Oracle test has very little to do with reality, the test software is not useful for anything else. This guide will serve you in you job if you work with Oracle databases so it has value.

It helped me greatly in the preparation. I wish there are bit more examples about new 12c features, would recommend the book anyway to somebody who has SQL and Oracle database experience and taking this exam.

Nice book

very good book, easy to understand.

its okay

Not even close to covering all of the material on the exam. Useless.

Not bad. You will definitely need more to prepare for the exam. This book does well as a concise review.
