Response final exam

Hi to everyone. I completed the course, unfortunately I lost 2 week because of my job, but I work so hard in this last week and the mflix project works perfectly. I done the final exam and I anwer correctly to all questions, but the system said to me that I have to retake the course.
Okay, I accept that, but I can’t retake the course because it is useless,I know the concepts and I have know the correct answer of all tickets.
To be honest, I’m disappointed.
I hope that your system become more flexible.
