Thanks to erpprep, I passed the SAP SM certification exam (Solution Manager) on the first try.
Honestly, I don't think SAP wants you to pass on the first try. I had a 5-week-live course and the information was overwhelming.
Luckily, I found erpprep. This site helps me familiarize the exam format, and the scenario questions are a tremendous help.
My advice, take the practice exam at least 4 times so you can see all the questions.
