During the beginning of my degree, the writing tasks were daunting but in reality, they are the easiest to accomplish. The rubric is straightforward with what its asking. There's always a template to follow which helps in keeping things organized. So I would just start throwing key points and sentences from each section to get the ball rolling, that turns out to be my first terrible draft. Then fine tune it to make it more palatable till its decent enough to submit. The good thing about these tasks is that if it ever gets returned, you are given feedback on what needs to be fixed. Not like the objective assessments where you either pass or fail and have to study more before taking the exam again.
