  • Clarification - slide005 of Week12 on lab exam marks

    Posted by Ashesh Mahidadia Monday 13 November 2017, 07:02:59 AM.

    I received few emails regarding the following slide, and realised that what I wanted to communicate was not clearly stated! So I have now modified the slide, please re-read the slide, in case you scored poorly in one of the lab exams. The overall aim is to help you pass the course, not to penalise harshly. Your final marks will be calculated based on your original lab exam marks, so depending on your other marks, you could still receive say PS, CR, DN or HD. In case your final marks are not enough to pass the course, I could increase the marks of the corresponding lab exam to 50% and calculate your final marks.

    All the best for the exam.

  • Week-12 Lab Exam

    Posted by Ashesh Mahidadia Wednesday 25 October 2017, 07:23:54 AM.

    Week-12 Lab exam is now marked (auto-marked) and ready for collection, see "examWk12q1" and "examWk12q2".

    Review : You can request a review if you find a mistake in the auto-marking. However, you need to properly outline where the auto-marking is wrong in an email to your tutor . You cannot say like - "please review my exam". You need to identify the problem, and briefly describe it in your email to your tutor. As we discussed in the lectures, you will not be awarded marked because you tried but could not develop a correct solution in the exam. Please note that there are many components in this course, like assignments, theory part, labs, etc. For prac exam questions, we expect you to develop correct solutions in order to receive marks.

    Prac Exam Hurdle: As we discussed in the last lecture, see here , even if you scored poorly (less than 50%) in both the lab practical exams, you can still pass this course. You need to score 50% or more in the final practical exam (programming questions), and later if required, 50% or more in the supplementary practical exam (programming questions). So, please focus and do your best in the final exam, all the best.

    Summary : The charts below show that many students passed all the tests. You can see the difference in performance between q1 and q2! If you did not score well in q2, you should focus on graph algorithms for the final exam.
