  • Guidance on Assignment 2 Enquiries

    Posted by Raymond Wong Friday 28 November 2025, 03:19:38 PM.

    As noted in the previous announcement, if you have any questions about your marks, please follow the instructions in the result email and attend one of the scheduled consultations (today, Dec 2, or Dec 4). Please avoid emailing unless absolutely necessary, as response times will be delayed.

    Despite this, we have received a significant number of emails requesting post-submission code updates, resubmitting and retesting, relaxed memory/runtime requirements, and other adjustments unrelated to the assignment specification. We have also received questions asking which tests or files were failed. While we have responded to many of these, we are no longer able to continue doing so, as our priority must now shift to exam setup, post-marking review, finalizing late penalties, and entering marks into the system.

    To clarify:

    • The marking script—very similar to the one used during marking—was released earlier. You can run it yourself to see which tests or files failed.
    • Your result email also indicates which tests were not passed.
    • As previously announced, if you are having trouble running the tests, please post on the course forum or attend one of the consultations.

    For example, some students have written: “I believe my output was correct, but I overlooked the space complexity requirement.” As stated in the specification: “Any solution that violates this memory requirement will receive zero points for any relevant tests.” To ensure fairness, we must follow the published specification. Allowing exceptions would be unfair to students who adhered to the requirements and completed extensive testing.

    More generally, we cannot make individual adjustments based on post-submission corrections, even if the change appears minor. Some other students might encounter similar issues, and evaluating the impact of each individual correction would introduce inconsistency and subjectivity into the marking process.

    As mentioned in the final live lecture, assignment code may be manually reviewed and marks adjusted if a student performs well in the final exam -- particularly on the programming question. This process provides an objective way to distinguish between genuine minor oversights in the assignment and more fundamental issues, based on demonstrated understanding in the final exam.

    If you have further questions regarding the marking tests or your assignment results, as advised, please attend one of the scheduled consultations.

    As noted in the last live lecture, in addition to the consultation session this afternoon, two special consultation sessions on Dec 2 & 4 have been arranged for any final clarifications before the exam. Please see the Timetable for details.
    We encourage you to make use of these sessions, as they will be the final chance to discuss questions related to the course materials.

    In the meantime, you can run the tests on db-perftest by navigating to your folder with the Makefile and source files and running:

    ~cs9319/a2/automark 
    

    Discussion of the tests can be found from the last live lecture recording. If you have questions about running the tests, please post on the course forum or come to this Friday’s consultation session.

  • Moving Today’s (November 21) Consultation to Online

    Posted by Evelyn Hao Friday 21 November 2025, 01:49:34 PM.

    Due to some personal matters, I won’t be able to hold today’s consultation in person. Instead, we’ll move the session online at the usual Tuesday link. I apologize for this short notice and any inconvenience this might cause, and I appreciate your understanding.

  • Reminder: Assignment 2 due tomorrow at noon

    Posted by Raymond Wong Tuesday 11 November 2025, 06:28:04 PM.

    A reminder that Assignment 2 is due tomorrow at 12:00 noon .

    As discussed in the live lectures, this type of assignment -- where we benchmark runtime performance and memory usage -- makes plagiarism relatively easy to detect, whether from other students or online sources. Each year, we identify a few cases and refer them to the university for formal investigation.

    Please ensure that the work you submit is entirely your own, as stated in the spec. Submitting work that is partially or wholly copied from another person or any external source is strictly prohibited and will be treated as academic misconduct.

    Thank you for your attention, and best of luck with your submission!
