I recently took an SAP certification exam and found Erpkite to be immensely helpful in my preparation. The website provides a wide variety of practice tests, which are tailored to the actual exam. The questions are designed so that they cover all the topics that one needs to know for the exam. Moreover, it also offers detailed explanations for each question, which really helped me understand and remember the concepts better. I would definitely recommend Erpkite to anyone preparing for an SAP certification!
