Let's don't take UITM into account. Let's discuss this as a general university.

I know sometime there will be cases where lecturers did not consult other lecturers and go and give assignments all in 1 time

Like there is 5 subjects.

Ngam Ngam all 5 of them give assignment on Monday, finish on Wednesday.

Even straight A students and people with good time management will not able to finish all assignment by Wednesday unless 3 day no sleep.

Luckily we complaint and lecturers understand and agreed to spread out a bit the assignment. Like Subject 1 is Mon - Wed , Subject 2 , Wed - Next Monday...etc..
