Its not that hard to passed OCP !
Hi Chester,
I passed O7.3 and O8 DBA without experience !!!
and I didn't attend full class for that, I just attended
SQL/PL SQL and Oracle Administration(i.e. first 2 paper) classes and rest of all i prepared at home(I've computer at home)!!
I used Jason Couchman's book, Exam cram and Off course
STS.
You can buy STS from http://www.stsware.com and
exam cram are available at http://www.amazon.com
http://www.chapters.com, http://www.fatbrain.com and any local computer book store.
You should go for exam, don't be scared bcoz of its
cost ($99)!
HTH,
Good Luck :)
