I am very surprised by the service of erpkite. It is the best practice for SAP certification exams I have found so far. It offers lots of questions and answers from past exams with detailed explanations on the solutions. The explanations are clear, concise and to the point, which helps me understand what to do in similar questions in future exams. I am writing this review after 2 month and It has been the amazing experience with the erpkite service.
