Topics learn through mock tests

The topic Describe and Design Wireless Architecture for Real time Applications and Post-Deployment Site Survey in the Cisco 300-360 WIDESIGN syllabus is very very difficult for me earlier. I could not answer question on it. But thank you to the Designing Cisco Wireless Enterprise Networks mock tests and unlimited attempts feature. I write again and again exam and learn where i was wrong. I could clearly pass the exam without any difficulty.
