PER VMWare website:
“Participation in a VMware authorized training class is REQUIRED for VCP certification. Candidates who take the VCP exam without a class will NOT be certified or confirmed by VMware”
When I took the esx2.5 class, it prepared you for the exam.
I didn’t take the exam, but my co-worked did. He said 90% of the class was on the exam and the other 10% was what we learned while supporting it.
So don’t waste your time taking the exam if you aren’t willing to fork out the money for the class.
