As I mentioned in the header this is my third Activate Project Manager Certification. First were MM and WM.
This time Activate Project Manager certification were easy - in both I have gained 88%. So with such attitude, if you buy premium exam and prepare yourself, you can feel relaxed and confident at the real exam, even if you prepared yourself only with erpprep.
I decided to take a risk and bough C_ACT_2403 premium exam and it was a real success. So, when I need another SAP certification, I will use erpprep. Definitely :)
