My way of studying is this

DES-4122 practice quizzes come with not only questions but right answers as well. So i was self assessing myself. The correct answers helped me clear my doubts and got me to understand that this is something very helpful in revision. I was from this sect that believes in rotting the syllabus. But the quizzes gave me enlightenment and support to clear the Dell EMC PowerEdge Specialist for Implementation Engineer certification exam.
