Due to the nature of the subjects I have chosen as well as the structure of my subjects at my school, I didn't really get much assignments throughout my HSC year, but I would usually make notes for the science subjects at the end of each week as opposed to every day, and I would write it on paper-for me, it helped a lot with my memory. But basically during the school term
1)I would assign at least 90 minutes of rest after school-so it is like 30 minutes for afternoon tea and 1 hour for dinner, I would make a to-do list of all the things I needed to do that day-preparation for assessment, homework and study(extra questions), it is usually on the subjects I do on school that day-and the list is always slightly longer than realistically what I can achieve-because I want to push myself to maximise my time efficiency
2)I would take a 5-10 minute break for each hour of study, and during that time, I would either re-hydrate myself or procrastinate on the net to relax and refresh myself-time management and planning of each session-whether mentally or on paper is extremely crucial
3)I would write down any questions I found hard or I didn't understand, and I kind of regret the fact I didn't ask these questions the very next day, but basically I would accumulate these questions, say over a period of several weeks, by which I would then ask the teacher in one go or I would try to solve the questions myself
4)I would also try to do practice papers and past HSC exam questions on the topic I was studying for-whether it was chemistry, physics or maths as soon as possible(I.e. when I did my textbook questions as well as other extra ones)
5)I would often set aside the weekend for more intensive studying/practice/reading ahead, but in general, you have to consider whether the homework will be beneficial to your understanding-because sometimes teachers set random homework that wastes time and doesn't add to your understanding, and under these very rare circumstances, I choose not to do it because of the often significant amount of exams/assessments tasks I had to study for-prioritising is everything
But I think the most important element of studying efficiently is to listen in class to what the teacher have to say, because if you understand the content in class, you don't have to waste the time to re-learn the concepts yourself at home, and of course-you need to find a source of motivation and consistent self-discipline to ensure you consistently study very hard both during the term and the school 'holidays' to maximise your chance to getting the best ATAR possible. Best wishes for the year
