Dear Allan

It is nice to meet you on this class and I am so happy to take this class.
I would like to ask few questions that did i get 9,10 of question? i'm keeping confused that 9,10 of questions are still  scoring or not.

and i couldn't remember 3,6,7 of the questions. Could you  explain why i'm not correct that answers please?
and 7 of questions ask that noise is a major problem. i remember yes i replied answers because we learned about noise

students might be noise when they have pairwork so i thought noise is major problem. 

could you teach me more please?
Thank you.
