Many people have the same impression on CCNA certification of which it’s merely a certificate that doesn’t help specialty acquisition very much. However, take myself for instance, though I am graduated from information department and in charge of the related job for some periods, I’ve found many unresolved problems in my work because I didn’t establish correct fundamentals but acquire vague concept before via reading unfiltered textbooks. Thus, I resolutely decide to correct my previous concept.

During the preparation of CCNA certification test, Paul really benefits me very much. Here I really want to recommend original manufacturer authorized course and textbook. Through the careful study of these teaching materials and teacher’s careful instruction, many incorrect concepts that I obtained before are all revised.

Actually I also read the other popular textbooks but I find the knowledge that I obtain from these books is much far away from Cisco original manufacturer authorized teaching materials and Paul’s careful instruction. Eventually, I also passed 640-802 CCNA certification test.

Maybe certificate only means one piece of paper for most people. However, it refers to my built knowledgebase during my preparation for the test. I think it is the most important part for me.
