Covered my knowledge in weak areas

I did not know much about Business Case (BC) Theme, Quality (QU) Theme, Change (CH) Theme while preparing for PRINCE2 Practitioner certification. The mock tests available online had questions from all the chapters defined by the PRINCE2 Practitioner. So, it helped me get practice in the way i desired. After practicing for a few days on PRINCE2 Practitioner, my score started getting better and i also got a different point of view of the same chapters.
