How was week 1? Head still spinning? Too easy? Neither? Both? Whatever the feels the real deal starts week 2 after the compulsory unit introductions are over. Week 1 should have given you a clear indication of the workload required for each unit you're taking, which brings me to scheduling your week.
Whip out your semester plan (or put one together if you haven't already, at a minimum do this), and look at how assignments are spaced out: what requires attention every week, what needs more than a regular week's effort, what's due soon etc. Consider how much time you will need to go through each week's material per unit, which ones need more time and which are lighter, then draw out a weekly plan and earmark regular timeslots for going over the material.
Note: when estimating how long a task/reading/online quiz etc. will take give it a bit of a buffer, e.g. if you think a task will take an hour add a bit of extra to this as you'll probably soon find out reading academic texts and coming back to topics after a few day's break will take longer than you thought.
Prioritise what's important, make sure you allow more time for your core units and for those you really want to shine in. For an example: out of the four units I have taken it's already crystal that one of them will require probably twice the effort as the other three, and as it's also likely part of my future major I have to put some serious focus on it. So in my weekly plan majority of time available will be dedicated for this unit, this after factoring in other weekly must-delivers.
Here's one of my main time management tips: if you have a prac/lab/tute/etc. which includes an assessment item to be completed afterwards, finish the task the same week even if you are given more time to submit. Chances are the same unit will require more postlab or similar work that gets handed out the following week - better get the previous stuff done before that hits your desk. Also this way you do not end up with 879 online quizzes and prac reports to submit by the time you hit STUVAC. Because that's enough to make a grown man cry.
