OCP - 8 or 8i? Self Test Software?

Two questions:

1. I've been studying for the Oracle 8 Database Administration Exam. = However, we've just installed 8i. Do I have a good chance of passing the = 8i Architecture and Administration exam without having specifically = studied 8i capabilities? I haven't done any of the OCP exams yet.
2. Is the Self Test Software practice exam a reasonable facsimile of the = real exam? I'm doing pretty well on it, and would like to know if that = means I'm almost ready! :-)

Thanks! And, please, let's not start another discussion on the validity = of the OCP. I have to do it - it's in my job objectives for this year. = Besides, I need the knowledge.
