Hello, Allan :)

I have a question about 'Things to keep in mind when making and using work sheets'.

what is the meaning of 'Not all work sheets should be written on'?
It is hard to understand just by explaining in the lecture.

Please tell me in more detail and easier.

and I also wonder 'advantages of flash card'.
It was the quiz in module 8. I wrote them but I am not sure.
Because I can not remember of learning about it exactly.

Could you explain it again?

Thank you, Allan :-)
