Hello Muhammad,
I am not familiar with that program, so cannot comment about its quality. I began my career as an E&P analyst, and ended up being a ranked analyst by Reuters (they rank buyside analysts), and I did not have the ERP designation. Instead, I studied the industry intensively and thoroughly read "Money in the Ground" and "Security Analysis and Business Valuation on Wall Street" by Jeffrey Hooke. Both prepared me very well for the industry. That said, designations are very important to some hiring managers, and so it may make a difference.
I am sorry that I cannot be more helpful.
Yours, in service,
Jason
