hey! i passed 1z0-899 (ocewcd) with 96%..
To study, i used Charles Lyons book wich i think is very good, but some topics like http only cookies are not covered (i've got two questions about this in the exam).
Enthuware kit is a must, it has a lot of questions VERY similar to the exam and is very very good. My average score from enthuware was 80%. The difficulty level is the same.
Regards, and thanks to all of you for the info in this site!
