[Cs3] extra assingment for grad students

[Mikhail Nesterenko]

for the grad student(s) in this course,

You have to complete an extra assignment (13th lab): "Decorated
Search" that has just been posted on the lab's website. The deadline
for the 13-th lab is the same as for the 12th (midnight Friday this
week). The lab is worth 10 points. Your total possible score for the
course will be 10 points higher than undergraduate students'. So it is
not extra credit work.

For undergraduate students. The lab is optional. However, it is not
extra credit work either: the score for the lab will not be counted
towards your grade. 

thanks,
