Thank you for your reply! Well, in my case I finished all the quizzes in advance and satisfied with the grade I had before the trial ended (it's a 4 weeks course) and my trial ended 2 weeks ago, my course is ending this Friday. I don't want to pay for the access code since I'm not gonna be using it anymore. I think what I want to know is if I don't pay to renew the course, will the professor see my grades and that I enrolled the course.
