Hello @gemissorosco9 
Welcome to the Canvas Community. Thank you for posting your question. I am not sure if you were aware, but you have posted your question to the global Canvas Community website where people from all over the world come to ask questions, suggest new Feature Ideas, collaborate with others, write blog posts, check out "how to" Guides and video tutorials, and a whole lot more...all about Canvas. Unfortunately, the vast majority of Community members wouldn't be able to help answer this because we do not have access to your school's Canvas environment or your course(s) in question. Test settings are typically determined by your instructor, and so you would want to reach out to him/her directly to see why you (and most likely your fellow classmates, too) may not be able to access the test. Please check out this Guide: How do I get help with Canvas as a student?
I hope this information will be of help to you, Gema. Please let Community members know if you have any questions about this information...thanks!
