It is easy to learn out of them

I thought how will i cover the difficult topics of Unicast Routing and Routing Policy and Manipulation in the syllabus of the Cisco 300-510 certificate exam. But after doing multiple rounds of mock tests on 300-510 online, i completely forgot that i was weak in those topics. The practice tests are so beautifully prepared that they help me prepare for the exam without a single glitch. I think everyone should try the practice tests before appearing for the actual exam.
