Hi, I am planning to get my 35 contact hours. I was wondering whether a PMP workshop (simplilearn or knowledgewoods) is actually worth it or is it enough to prepare rigorously with the right materials (Rita, PMBOK, various mock tests) to pass the exam? I am sufficiently motivated to study on my own and have already completed Headfirst and Rita (average score of 75%) once. Just wondering if a workshop would add any value.
