I am currently taking the BSc in Computing course and I have 2 modules giving me problems. The Linear algebra 1(MAT1503) and Introduction to Programming 1 (COS1511)

The final assignment for MAT1503 is coming up but question 1 and 2 are impossible to do and question 3 and 4 are exactly the same, though I think they did address this one.

And for COS1511 the final marks for the asessment 4 is just wrong. A full 19 marks were incorrectly marked as wrong even though I tested them afterward.

Emailing the lecturers is also just futile as they never come back to you.
What am I suppose to do?
