Hi @Goutham VS

You have to use same email address in Pearson VUE, .i.e.., Which is used in PDN.

Example; If you used email in PDN: abc @ test.com, you have to use same email in Pearson VUE: abc @ test.com

Always we have to use same email address in both accounts.

Please login by using below link
