Our group was supposed to submit our Semestral Project, 1
project for 1 module that kind of project. But we couldn't
integrate on time, and many error occured. So we handed in some
junk to tide over. Some other group purposely corrupted their
program, so they could their backup ( enhanced ) copy on the
presentation day. 
Then my friend from another group, also same class. He told the
head Lecturer for that module that his group submitted already, but
got a lot of error, and many functions not working. The Lecturer
said it was okay, they can go back and update their program, on the
presentation day itself they can use their backup copy to present
if the one they submitted is not working.
This confuses me, why did he meant by "They can go back and update
their program, on the presentation day itself they can use their
backup copy to present if the one they submitted is not
working."
Update liao, is still called backup copy meh? 
Then later we heard that other classes teacher said that the 1 they
are submitting is just for the sake of submitting, they can go back
and enhance 1.
So later my friend asked the head Lecturer, what if we cannot
finish on time, the Lecturer said, its okay. Hand in on Monday lor,
then later the Lecturer think think then said, I think you throw it
in the submission drive, I want you all the enjoy your
weekend.
So in the end, we hand in some junk, that does not even have a main
page...
So now what? Continue doing?
