OKAY so I'm actually not the best person to ask for this. I was not one of those people who studied for hours on end around the HSC season. I actually was pretty lazy during most of that time, and gave myself ample rest time. I saw people studying for like 8+ hours a day, EVERY DAY. I was probably doing max 5 hours in one day at the peak.
I didn’t follow a study plan, just a to-do list which I neglected at times... I prioritised my study by what I felt like at the time + fixing weak points, which is probably how I ended up neglecting other things. But being consistent is the most important thing. I was locked in since the beginning of year 11, and didn’t procrastinate. I could get away with being sick the week before internal exams because I had already studied enough to be okay!
