Thank you erpprep!!!!!
I just passed my real S/4HANA 2021 for Management Accounting exam with 91%.
what is the same things i found in erpprep and Real exam SAP C_TS4CO_2021:
1. very similar question sets.
2. very similar exam situation.
3. high reliability, high validity.
So, practice more and more, you can definitely get high score.
