More clarity on certain topics

It is difficult to know how much I know about a certain subject unless and until i give a quiz on it. Giving 1Z0-591 mock tests really really helped because it had questions from every area of the syllabus and i understood my weaknesses in a better fashion. OBI are two such topics where I needed help and giving practice questions on a regular basis helped me pass the 1Z0-591 exam!
