there are some things that will make sure that you sail through the preparations and the actual exam. First of all, preparations will never be complete without giving mock tests. Here, i would advise not to go for pdf files but actual online mock test. I found this site amazing as it not only covers the syllabus with Updated Cisco Certification Questions but also creates an ambiance during test, which is quite necessary if you do not want to get nervous during actual exams. All my friends have tried the site and have given positive reviews to me. I would advise aspirants like me to try 300-180 Mock Test here.
