I'm starting my Oracle Certification - want to be done
by end of November. I completed phase 1 from Couchman
book and answered all questions in his related Exam Questions books - there are two practice exams for each
phase. Is this enough? I don't want to spend more money
on the STS software. Are the STS questions different from
the Exam Guide questions.

My background is in Electrical Engineering, and I have
extensive unix experience, so I'm finding the going fairly
easy so far.....
