 I miss you guys, I like to see you in the class, to hear how are you doing, how has it really come with you, your family, how do you feel these days? Hello, my name is Saad Hassan, I'm professor of physics. It takes more effort from us to prepare for these classes, especially when it comes to advanced course. To put it on Island and to share a student what we can do because of the limitation of the time. So we prepare more for these classes. We are continuing at the same thing as we are teaching eye to eye with the student. All of the students, they come to classes, they ask, even they share their opinion either by microphone or by writing notes and they ask a question. The same thing of advanced courses. So it is good experience for us at AUS, both at the same time for faculty and for the student. Good luck for everybody, best wishes for everyone.
