User must log in or register

Thank you for the “Customer must be logged in to take the quiz” function.

The message is shown as below:
“You need to be registered and logged in to take this quiz. Log in or Register”

However, when I pretend to be a new customer and click the “Log in” or “Register”, the hyperlink of the “Log in” and “Register” brings me to the “WordPress admin login page”.

May I know how to change the URL of the “Log in” or “Register”?
Is there anyway I can change it in the Plugin Editor or add a code snippet to override it?

How to write the snippet to override the URL to the URL I want?

Thank you so much.
