I was very weak in certain areas like Case Management, and Application Development etc. The questions in the mock tests here covered the entire syllabus of CPBA Exam. This helped me cover-up the weak areas and even strengthen the topics i knew very well. At the end of the practice of 2 months for Certified Pega Business Architect, i mastered the syllabus and started achieving the flying colours. I am quite relieved with my hard work here.
