I am a premium member of the online practice tests on the vmexam.com and seriously, this has been my best decision ever. I could practice again and again on the same set of questions to clear my doubts and also build the foundation. I liked the way questions are exactly as they are in the actual Red Hat Certified System Administrator certification exam. So when i was attempting the actual exam, i did not feel like it was my first attempt, but i felt as if it was my hundredth attempt and i was not scared at all. This helped me clear the exam with a very good score at first attempt itself.
