I think that the exam cram book by Darrell L Ambro is a great prep for the test. It goes over the material and has a sample test for each exam. Its something worth checking out.

When I passed the tests I used both 3rd party information and the Sun manuals provided by the classes.  I'd suggest you try using the Bill Caulkins Sol 8 study guide published under New Riders.  

I'd augment this information by thoroughly reading the Sun Manuals on chapters you dont understand or know there is alot tested there.  The test uses the EXACT same lanuage that the Sun Manual does.  So it will help jog your memory for the right answer by knowing it.  However, the Caulkins book is much easier, (format, info. etc) and has more xplaination to give you an Understanding.  U really need this to pass the exam.  
Good Luck,

Hi there,

this book I can really recommend. It's not very cheap (50 bugs) but it's worth it.

Sun Certified System Administrator 8.0 Study Guide
ISBN: 0.07-212369-9

With this book I passed part1 and actually working on passing part2 with that book.

Hope that helps

Best Regards
