I am a big fan of the Erpkite website. I was using it to prep for my SAP exams. The practice questions are really effective and have helped me increase my score. The site is a treasure trove for anyone who wants to take the SAP certification seriously. If you’re studying for the SAP exam I would highly recommend Erpkite. The practice questions are of the same difficulty as the real thing and have a lot of additional information that tells you why an answer is right or wrong. The explanations really helped me to understand difficult concepts and avoid confusion in my studies.
