My overall grade in communication bootcamp has reduced drastically

I had a total overall grade of 84% yesterday, but today it is showing 65%, can I know why, please?

As mentioned before here, @venki.891981 don’t worry. This is a common thing. The overall grade on Classroom portal calculates the total marks for ongoing and newly opened quizzes and assignments. You must have new quizzes or assignments that have become active or some submissions are yet to be evaluated.

The overall grades will fluctuate based on these points. Thus, don’t focus on the overall grades but on individual scores, specifically focus on your Certification exam for Communication Bootcamp once it becomes active.
