Good news: I took and passed my latest C_HRHPC_2305 test.
After the exam, I did a small write-up about the exam process and the positive role that ERPPREP.COM played in preparation. I sent this to our resource director and a couple other folks in our company.
If others have the need/desire for any SAP certifications I know that ERPPREP.COM will be on the radar. Truly worth.!!
