Create a PDF in Illustrator by using Save a Copy
Save A Copy allows you to save your Illustrator file as a PDF for sharing with viewers who do not have access to Adobe Illustrator. Your PDF can be shared by email or easily uploaded to Google Classroom/Blackboard for review, critique, or grading.
This video also shows how to organize artboards (your "pages") in Illustrator so that your PDF is organized in your intended order.
