Hi,
ERPPrep is very helpful for clearing SAP XM-Fundamentals certification, one must practicing the tests on erpprep untill you can score till 85% and above, go throught the books and keep on practicing practicals as well when you are chasing the difficulty in understanding the particular topics after evaluating your score by yourself (make sure you must revise topicwise only). It will definitely help you in achieving your target to be an SAP Qualtrics XM Fundamentals.
Thanks
