I think the students should copy the HW on the diary at once when the teacher is doing that on the blackboard. Is it possible?
Now, Ana is sitting at the same table with Harmoni!
Accord to Ana (p1g2), maths (g3), they will change to another classroom for their group. before the lesson finished, they have to copy down the hw at hw diary, sometimes, she will miss something as they have to leave that class and shift to another classroom and no time to copy anymore, sometimes copy from her classmate.
