It is easy to clear difficult topics

E-BUSINESS ESSENTIALS and ORDER MANAGEMENT topics were quite tough for me initially, before i actually started giving 1Z0-521 mock tests online. However, they eventually became easy and i did not even realize. Once when i scored well in a mock test, i came to know that i was able to answer the questions on these topics. My confidence shot up and i cleared the actual 1Z0-521 exam at first attempt.
