Reasonably priced comprehensive questions

When i started out in the industry, i did not have much money on my hand. Today, i am quite well to do, but since i have cultivated the habit of investment and returns. While preparing for the C_THR89_2505 certification exam, i wanted a resource that would yield good returns in terms of score without requiring much of my investment. So i opted for SuccessFactors Workforce Analytics Functional simulated quizzes. They are very helpful in helping me learn more about the syllabus.
