Marking guide for Assignemnt#2
==============================
(by Naim El-Far)


Dear students,

Please read the following before attempting to contact me requesting a
review of your grade.

  1.. Your code was tested with several mains to test individual methods.
The results of these tests have been automatically generated for each
student by a program I wrote to help me grade the assignments, and these
results are what the automatically generated output in the Grade.txt files
are. If the grade.txt file indicates a flag was raised for a specific
method, that means that your code's output did not match the model output
and that prompted me to manually examine your code. If the comparison result
came back ok, then you were given full credit or close to it depending on
other considerations such as for example not using binary searching.
  2.. For quite a few of you, grading your code meant debugging it to figure
out which function wasn't working properly. When doing that proved too
timely, the "blame" was spread over the suspect functions so for example, if
your update() wasn't working fine although your add and delete were, there
were partial deductions from all three. This is not to say that your add,
delete and/or update were all buggy, but that there was a bug in one or more
of them.
  3.. Some of you also received notes besides those in the Grade.txt file.
Those who did, I need to hear from you ASAP.
  4.. If you feel you deserve more points than you were awarded, then please
write me a detailed email explaining your case. I will in turn explain to
you where your deductions went. The most important thing is to actually
state your case when you email me and not just request a meeting.
  5.. For those who are unsure which part of their code is not working and
therefore unsure why deductions were made, then email me your student number
and I will try to better communicate with you where the problem lies. Before
putting yourself in this category, please review the grade.txt file and
contrast where the comparisons cleared and where they failed; this might
give you a good idea of where the problem is. A common scenario is for
example to have a clear comparison for the add method, but a flag for the
delete method. This would explain a flag in the update method which
functions by deleting then adding to the data file. Generally speaking,
please examine the flags before declaring that you don't understand where
the deductions were made.


 Fair enough?



Thanks

Naim
