I'm doing a really boring online project management course. I was feeling pleased with myself because I'd studied hard and passed the mock exam but then I found the exam rationales didn't even match the questions. When I queried this with the company they said they had hundreds of people doing the course and I was the first to complain and perhaps it was an IT glitch. I have a set amount of time to do the course and I don't feel I can book the real exam until I can review my answers for the mock. I am really losing faith in the company and wondering whether to continue or whether I should refuse to pay for the course as it was bought on the credit card. What would you do?
