Postpone Your Lesson!

Hi all!
These few days I've been trying to work on an e-learning UIUX design and still deciding on some things that I still can't seem to get it right. So then I thought, maybe I should make a design for rescheduling or postponing a lesson when a student can't make it to the online lesson. I really want to explore this idea though because due to the pandemic, a lot of lessons starting from music school to language courses are done online.
