Was weak in 17% of the 200-401 syllabus

Because the topic Maintain Appropriate End-Devices and Industrial Network Infrastructure Devices in the syllabus had a weightage of 17% in the actual 200-401 certification exam, i was very weak i thought. Because if i answers questions based on this topic wrong, i am doomed. But thankfully the IMINS questions gave me a proper and good understanding by the means of practice which helped me clear all my doubts and took me on a level that i am clearer now.
