Welcome to this online classroom.
As I have said, this surface is established for sharing extra materials with you. I hope, this will help you deepen the topics we cover during classes and gather a lot of pluses that you can turn into 5's.
If you have any questions, please, feel free to ask me here or via e-mail ( firstname.lastname@example.org ).
Anyway, I hope the time spent together will be beneficial and enjoyable for you all.
See you soon.
