Was weak in 30% of the 300-535 syllabus

Because the topic automation APIs and protocols in the syllabus had a weightage of 30% in the actual 300-535 certification exam, i was very weak i thought. Because if i answers questions based on this topic wrong, i am doomed. But thankfully the SPAUTO 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.
