Any topic every topic covered practice

I know not the english language. I know not how to practice for 300-075 certification exam before. I got to understand only through the CIPTV2 practice tests that i should beat the competition. So i opted for the tests that help me prepare the tough topics of Describe and Implement Centralized Call Processing Redundancy and Describe and Configure a Multi-site Dial Plan for Cisco Unified Communications Manager from the syllabus. In the end, i was able to score high. I will continue the premium membership.
