Yup. Good general overview.
Points you in the direction of additional materials on the net. Gives you a good idea of what the main focus of the exam will be.

Take a look at awesec's review of CEH iclass. He has provided links to various study materials he used. They'll be useful for you too.

I've heard that CEH v6 covers almost the same topics as v5. The extra modules added are for self-study only and won't be asked in the exam. Also, take a look at the CEH board. You'll find a lot of helpful stuff there. http://www.ethicalhacker.net/component/option,com_smf/Itemid,54/board,2.0/
