It is easy to learn out of them

I thought how will i cover the difficult topics of Infrastructure services and Infrastructure maintenance in the syllabus of the 200-105 certificate exam. But after doing multiple rounds of mock tests on ICND2 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 mock tests before appearing for the actual exam.
