The prep logic course did a good job in preparing me for the IT exams and so I cannot fault them for that. I signed up for their unlimited access which was a good deal if you are going for more than one exam. The problem with the site is that they are bad about auto billing you. When you try to cancel, they ignore you. They just keep billing your credit card. You will need to cancel the card to stop payments. I would say just get the single certs and not the unlimited access
