I tried a couple of practice test providers but found the erpkite practice tests to be by far the most informative. They are written in a way that is enjoyable to read and always has me wanting more. I highly recommend it if you are looking for a good practice resource. I am a huge fan of sap and have done extensive research on the best certification training company for me. After looking at other popular companies, I realized that erpkite offered the best content and practice answers for my needs.
