Hello Harrison,

## I am reaching out on behalf of my classmates to kindly request a sample exam template.

Sample examination are available on the University Institutional Repository at: https://dspace.unza.zm/collections/c9760974-ada2-446b-a853-5100cd678273

I am not sure I understand what you mean by template, however, I had mentioned that the class theory test is a good enough sample of how you should expect the final examination to be structured.

## If possible, could you please share a sample exam or provide guidance on the structure and key topics we should focus on.

We had a discussion of what topics to expect in the final examination during our epilogue class: in the event you missed it, please see slides on The Moodle. That being said, I am sharing a screengrab from one of the slides

Best wishes,
Lighton

Good Morning Sir,

We would greatly appreciate any resources or insights you could provide to support our preparation.

Hello,

You shall all have access to your test #1 scripts tomorrow, as this is when I shall get the chance to drop them off at the department.

Once you have access to your scripts, you shall have the opportunity to request changes to be made.

On a related note, I shall only finalise compilation of the entire course scores (attendance is still pending) by tomorrow.

Best wishes,
Lighton

Hello Dr. Lighton,

One question on my Test Script was not marked Q1.ii

The Image has the answer I wrote and similar code running on a google colab notebook. The first two images.

And I had also put in a similar query for my Quiz 03, but I was not responded to, you said you would, must have slipped your mind.

So the second set shows my Q1.i from Quiz03 and similar code from 6-code-unza25-csc4792-lecture-04-data_preprocessing_and_preparation.ipynb working

i am writing regarding my score for the Computer Science Data Mining course. As you mentioned, my score was not entered in the spreadsheet because the last digits of my student ID was unclear.

My correct student details are as follows:

Name: Nchimunya Sichilima

Student ID: 2021496481

As advised, I kindly request that my score be updated from 0 to 7. I have attached a copy of my transcript for your reference.

I’ve noticed that my CA mark is still showing a negative score under the topic and group selection section, likely due to the earlier reshuffles and challenges we faced during the process. I'm part of Group 34, working on the topic "Classification of Domain Subject Area Reference".

Hey Doc,

After reviewing the Continuous Assessment tracker, I noticed a few issues I would like bring to your attention

Marks for individual group selection,group selection, group|git+notebook, group dataset and group implementation were not allocated in the tracker
The calculation of the overall mark for Quiz 2 appears to be incorrect, it was recorded as 2,but based on the marking scheme it should be 2.5
Lastly I would like you to take a look at question 1(iii) of the quiz 2 I will attach at the bottom
kind regards.

Hello Jacob,

## 1. Marks for individual group selection and group selection were not allocated in the tracker

Marks in 2024/25 CSC 4792 assessments were/are ONLY allocated for successful completion of assigned tasks and/or assessments. Your group did not attempt the assessment by the deadline of August 5 2025 and as such, NO marks were awarded to you.
See screenshot at the end of this email

## 2. The calculation of the overall mark for Quiz 2 appears to be incorrect, it was recorded as 2,but based on the marking scheme it should be 2.5

Your LAB/QUIZ #2 score has been upgraded to 2.5 from 2.0. Please check and confirm with us

## 3. Lastly I would like you to take a look at question 1(iii) of the quiz 2 I will attach at the bottom

This has been reviewed
Your solution is NOT syntactically correct in any shape or form: no import statements; indentation is WRONG

Best wishes,
Lighton
