I want to update a vcp certificate before joining the course. I have vcp5 certificate. I’ve read the steps from a few sites. What I want to learn is, can I take the vcp6.5/vcp/6.7 exam without going to training. then I want to get vcp7. I want to upgrade my certificate without attending training. If I want to buy the vcp6.5 or vcp6.7 exam right now, can I ? Do you know a method without participating in the training, which exams can I take and keep my certificate updated?
