I had heard a lot about ERPPrep for SAP SuccessFactors tool exam preparation.
In January I paid to take the Recruiting Management Candidate Experience (THR84) exam, I took for at least 5 or 6 times more than 90% and decided to introduce myself, but I failed.
My next option was to take the Employee Central exam (THR81) and speaking with some other colleague, they told me that they had taken and passed the exam and that they had also prepared it through ERPPrep, so I paid to take the premium exams and I can say that as of July 28, I am certified!!!!
Kind Regards
