I took the SAP SF LMS exam after having rigorously through the course content and could only manage to get 54, hence I failed. I discovered that the manner in which the questions were asked was different and needed prior preparation before tackling the exam. i searched online for preparation facilities and came across erpprep.com. i took the exam again and managed to obtain 80%. I highly recommend going through the preparation exercises available here and score 100% before taking the exam.
