erpprep.com is best place to practice for C_TS4FI_2021

I am Akira from Japan. My advice to all S/4HANA Conversion and SAP System Upgrade desired people to have practice on erpprep.com. I especially liked case study based questions which helped me to understand each topic. I gain much confident on Manual Activities for SUM, SUM Monitoring and Troubleshooting, etc. I have scored 84% last week in final exam.
