It really depends on your experience. If you've worked enough with oracle, you might be able to take a test a week until you are done.
When I got certified (2 yrs ago) , I had about 3 years experience on Oracle. I scheduled my exams about a month apart and studied REAL hard between them. There is so much stuff on the exams that you might not use everyday. Som exams are really hard and you need those extra hints to get you above the passing grade...
Nothing is IMPOSSIBLE, bcoz IMPOSSIBLE means
I AM POSSIBLE!
I did it without experience within three months!
I also used Jason's book as well as Exam Cram
How much did you spent on eClasses ?
and what materials did you got from them?
Now a days, I'm preparing for 2nd paper of
OCP Application Developer.
Best Luck !
OCP DBA 7.3, 8, 8i, 9i
Sun Solaris 8 Sys. Admin.
I have 2 years dev/dba exprience with Oracle 8, but as maris89 said it is true there is so much stuff which we dont use in real life for which I need to spend time. I am confident I can complete them.
VimalP, about eClasses, it is free rght now as a trial offer on Oracle Learning Network. Go to the site of [url]http://www.oracle.com/education/oln[/url] and register for a web account then you can use this login at [url]http://ilearning.oracle.com[/url] to take eclasses. I am not sure if they are offering for developer, you can check it out.
