Best practical site certification guide

Hi guys, I just passed my FI certification today 06/06/2018 with 88%, and I can say that ERP prep are the best.
I tried to use a different website before and I failed. I was really insecure about ERP due to my previous experience, but you can trust ERP.  The questions are really similar  to the test and I do recommend to study both practice  exams full/min. 
Thank you ERP, now let's go to CO SAP certification.
