According to MyUnisa, the year mark is calculated from the first 2 assignments with a weight of 50 each. Does this mean that assignment 3 does not count towards the year mark?
Tutorial letter 105 which explains how the year mark is going to be culculated for COS 261C, was sent to every student. If you haven't received it get it from either despatch or myUnisa.
My point is that the service Unisa privide with the year mark on MyUnisa does not correspond to the TL. i.e. the the weight ratio is not indicated (50\150, 50\100 or 50\200 etc.)
We gave the people responsible for calculating year mark for COS261C weight ratio in your TL 105. Please feel free to contact the department if you get the wrong year mark.
