Good morning, @ParvinShadaram ...
Your posting leaves a lot for interpretation. Your subject line is "first section". I'm not sure what that means. Do you have a question for Canvas Community members as it relates to "first section" that we can help you with? If you are a student and you have a question about course content related to "first section", I would encourage you to reach out to your instructor directly. We here in the Community wouldn't be able to answer questions about the content in your course(s) because we don't have access to your course(s) or your school's Canvas environment. Here's a Guide on how to reach your instructor if you are a student: How do I get help with Canvas as a student?. Good luck, and please keep us posted...thanks!
