Persuaded me to give my best shot

I was giving the 210-060 certification exam for the sake of giving initially. But when i started scoring well in the CCNA Collaboration mock tests, i made up my mind that i will clear the exam and i will make my attempt not go in waste. So my final score in the mock test was 85% whereas my final score in actual exam was 91%! Whoa! It is a big leap!
