I've created a quiz with points for each question but i didn't get the total points in submission?

It seems you have hidden your total calculation.

You may try changing your form settings to show the value of the hidden fields when it is submitted.
Go to settings>Form Settings>Clear Hidden Field Values and set it to "Don't clear".

Please give it a try and let us know if the issue still remains.
