2. The assignments are the second and
eighth questions on Slide 6 and 7.
Please hand them over to the class
commissary in charge of studies first,
and then the class commissary will send
them to my email email@example.com in
a compressed package before March
The questions of the final exam will be
selected from the following slides.
