Practice access for two long months

I got to practice free of cost for two long months. I used every day to the maximum by giving IBM DB2 11 DBA for z/OS mock tests. These tests have questions from all the topics of the syllabus. It helped me cover the weaker areas too. After answering so many questions on IBM DB2 11 DBA for z/OS certification, i think that i have become a professional about the theory. I am waiting to apply them at my job.
