Deferred examination in 2020

The format of the Deferred Examination, to be held in the last week of the mid-year break, will be identical to that of the Final Examination. 26 students will be sitting the exam on-campus in the normal face-to-face format. 7 students will be using Examplify.

For all students:

  • The exam provides 60% of your assessment in CITS3002 this semester.

  • The total length of the exam is 2 hours (no additional reading period).

  • The exam is closed-book. You may not use any resources such as textbooks or prepared notes, but you may write on sheets of blank paper to help you plan your answers.

  • You will not require a calculator, or graph paper, and will not be required to draw any diagrams in your answers.

  • The exam has 4 questions of equal value (20 marks each), with each question having 2 or 3 parts. You are required to attempt 3 full questions.

  • If you attempt all 4 questions, only the first 3 questions that you attempt will be marked. Your 4th question will be ignored.

  • During the exam there is no opportunity to ask for any clarifications so, near the top of any answer, state any (unusual) assumptions that you have made in answering each question.

  • The subject matter of the questions has been drawn from lecture notes, the recommended textbooks, and laboratory and project work.

  • Lecture material from Week-12 (Cryptography's role in networking) is NOT EXAMINABLE.

  • The exam will not cover any coding. However, one of more questions may ask you to develop some pseudo-code, or code resembling Java, Python, or C. The syntactic correctness of your code will not be assessed.

  • The 2017 and 2018 final examinations are representative of the format and question style for 2020 (the exam of 2019 was a different format, open-book exam).

    Note that:
    • Q3b from 2017, Q3a from 2018, and Q4a from 2018, all required students to draw diagrams to support their answers. While the 2020 exam will not require the drawing of any diagrams, you should be able to provide written answers to these questions.
    • Q4 from 2017 addresses content that was not covered in 2020.
    • Q2b from 2018 addresses content that was not covered in 2020.

    Sample answers to the sample examination papers will not be provided.

For students undertaking their final exam using the Examplify software:

  • The exam will be managed by Examplify software on your own laptop or desktop computer.

  • You will need to get your Examplify exam password via LMS (not these unit webpages):

    See: Online exam support
    The password is released to you 15 minutes before your scheduled exam time via the unit LMS page.

    Once you enter the password:
    - you do not need to wait at the yellow screen with the big red button;
    - you do not need to wait for any instruction from someone else;
    - you can start the exam immediately.

  • The total length of the exam is 2 hours and 15 minutes, allowing 2 hours for the exam, and 15 minutes for you to upload your answers.

  • Throughout the exam period (excluding Sundays) a dedicated phone line will be available to provide support for student exams. The call centre will be accessible from 8am - 5pm Monday to Saturday and can be reached on (+61 8) 6488 1212. The call centre can help students with:

    - difficulties opening your exams;
    - addressing a disruption or incident during your exams; and
    - issues with uploading your paper.

  • Each question is to be completed by typing your answer into a standard textbox of unlimited size.

  • The way that questions are presented in Examplify may be a little confusing, because it allocates a new question number for each item requiring an answer. So, unfortunately, our exam's 4 questions each appear (in order) as 2 or 3 Examplify questions:
    Our Q1 - Examplify questions 1 and 2.
    Our Q2 - Examplify questions 3, 4, and 5.
    Our Q3 - Examplify questions 6 and 7.
    Our Q4 - Examplify questions 8 and 9.

Mid-semester test:

We did not run a mid-semester test in 2020, but here is a list of questions drawn from mid-semester tests in previous years:

Some sample mid-semester test questions.

Good luck,
