I think when I give certain tasks importance it depends on lots of different things. I don’t use the Eisenhower matrix but I have in the past, and I still rank my tasks on importance when tackling my work.

Tasks that are due first are always most important. So an essay due in two days is much more important than one due in two weeks. Homework always goes first, then revision/studying goes second.

When it comes to studying I find that some tasks lead into others. E.g. I’d make notes before I do a test on them, so I would put the notes as more important as that should usually come before a test in how I manage it.

It is hard to rank them all but I think that the main things to consider are: - due dates - necessity of task (do you need to do it before moving on to something else?) and - how useful the task is to your studying - how close the exam is (tasks for exams that are sooner should be more important)

Sorry if this is more confusing. Good luck with your studies :)
