Blackboard via the allocated folder. These files must not be in compressed format.
It is your responsibility to check and make sure that you have uploaded both the correct files.

words- hide characters- use different character sets or languages other than English or any kind of
manipulation).
Email submission will not be accepted.
You are advised to make your work clear and well-presented. This includes filling your information on the cover
page.
You must use this template- failing which will result in zero mark.
You MUST show all your work- and text must not be converted into an image- unless specified otherwise by
the question.
Late submission will result in ZERO mark.
The work should be your own- copying from students or other resources will result in ZERO mark.
Use Times New Roman font for all your answers.
