3rd Crtification with this platform successful

As I mentioned in the header this is my third Certification. First were MM and WM. 
MM and this time BOBI certifications were easy - in both I have gained 98%. In MM only 4 questions at the exam were new for me, in Retail 0 questions were new, i.e. all real exam questions were listed in at erpprep.com.
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 BOBI premium exam and it was a real success. So, when I need another SAP certification, I will use erpprep. Definitely :).
