If there were no 1Z0-071 practice test, i would not have been able to do anything if there were no online practice tests. It has been a joyous ride throughout the two months. There was so much to learn from the practice. Firstly, i got punctual and regular. I did not miss the test just for fun or laziness. Secondly, my knowledge expanded and got comprehensive. If i know a subject, i know it completely. There is nothing gray, it is all black or white. All this helped me clear my certification exam clearly at 1st attempt, that too at 86%.
