Practice tests became an instrument

I graduated from a university and i took up a job that was on offer. I could not do much further in three years. Then i opted for giving cisco 300-620 certification exam. Day after day i studied the syllabus which was huge and vast. Then i came across Cisco DCACI practice tests that were made for novices like me and it did change me the way i practiced for the exam in a concentrated manner.
