The PVOnline Gradebook is explained thoroughly in your course syllabus. All courses have a link to the gradebook at the top of the course front page.
You can also access the gradebook from the Administration Block on the left-hand side of the front page.
Your gradebook is set up in categories. Your teacher has decided on the number of categories and the weight (percent) each category counts toward your course grade.
Your teacher can leave feedback for you in the gradebook or in the assignment you submit.
Whenever you have a question about your grade or the gradebook, contact your teacher.
