hOW DO I GET TO THE WEBSITE WRITE TEACHER FOR THE EXERCISE COMPREHENSIVE GRAMMAR CHECKPOINT

We have no idea. We are not connected in any way with Axia or any other school.

Check your Axia materials for the website.

If you'd like to post the questions and your answers, we'll be glad to check them for you. We have had these questions posted and our tutor, Writeacher (and others), have checked them for students.
