Changed my world for the better

Just a year ago, i was feeling stuck in the job and did not know what to do with the knowledge i have when a colleague asked me to prepare on the cisco 350-201 certification based mocks t clear the Cisco Certified CyberOps Specialist - CyberOps Core (CBRCOR) certification exam. I mocked him but after him persuading me, i was able to learn how things have changed for me.
