A must for getting the Certification

I just got the certification last weekend with a score of 77%, thanks in a high percentage to the certfun exams. There are lot of questions very similar to the exam, and make you focus on the important things you must know about core services. A purchase that worths every cent even if you don't want to get certified. I must add that I didn't have any previous experience on hpe or knowledge.
Warm regards and thanks a lot Certfun!!
