I am from Spain and i was worried whether i will be able to clear the IBM Cloud Professional Developer certification exam. I had quit my job recently and so my confidence had dipped quite low but i did not want it to affect my practice and performance in any manner. So i started practicing on questions in the first phase, in the second phase, i started reviewing the questions and then my performance improved to great levels. And after scoring 79% in the actual attempt, my confidence was so high that i even cracked the interview and got a well paying job also. I have continued the premium membership to get more benefits.
