Hello @karensevilla Welcometo the global Community of Canvas users. You have posted this question in a place where users from across the world meet and discuss Canvas. It's a great place full of fantastic people and resources and if you are interested I would recommend our Getting Started page.
However, because of this, you are unlikely to find someone who is familiar with the specifics of classes and policies at your institution. I could not tell from your profile information what institution that is, but I would recommend you start there for an immediate answer to your question, and return here when and if you would like help with Canvas.
Because there is not a single right or wrong answer, I converted this post to a discussion. It's great having you with us and please let us know if there's anything else we can do.
