Hey, I would just like to drop my advice.
Do not do Society and Culture. if you think you are capable of doing English Advanced, then opt for something with a bit better scaling such as Studies of Religion 2 or even undertake Eng Ext1, it honestly won't feel like much.
I was a pioneer of the new 3-assessment for y11 thing NESA did and more units you do better chances you have at acing y12.
definitely think about picking English Extension 1, aim to do high scalers that you think you will enjoy.
As for Languages, unless you are very good at learning new languages, you shouldn't really risk a Beginners course. Furthermore, do an ATAR subject instead of Photography or Ceramics.
Personally, some subjects that I know off are very easy and scale a little bit up are
- Business Studies (memorising can get you very far here)
- SOR 2 (barely any content, easy to do well)
- Information Process and Technology (don't be put off my everyone in this forum saying its a low scaler, it barely has any content and is an absolute breeze to study for)
- Legal Studies (surprise, surprise, again very easy to do well with consistent study)
- PDHPE (need to memorise body parts and stuff, but nothing hard)
- Chemistry (not as hard as its portrayed to be, if you are shit at it, get a tutor, can give you very easy marks given you put in the work)
FUN FACT:
Teachers and everyone will tell you that "choose subjects that you like, blah blah," that is true to an extent, but the HSC is a big game. To be good at any game, you need a strategy and need to make sacrifices. Don't be afraid to spend money on tutoring, resources, chances are it'll all be worth it in the end. The HSC is a game and you need to beat all the other players, this means ensuring you have an edge or advantage over everyone in your grade, I.e. either choosing unpopular but easy subjects so you can rank high or really competing with everyone. Ranking are as important as your marks, in some cases even more important. Take as many units as you are allowed to and make sure they all count. Be nice to your teachers, build a connection and be respectful. Don't be vicious while competing for marks, do it low-key.
Look into online HSC Subjects that you can do, it will take serious load off your shoulders for school.
You just have to work extra-hard in Y11 and Y12, after that it'll be very good.
More advice I can give is, especially for Biology, set a goal to summarise the whole syllabus within the 6 week holidays coming up. This way you will be very significantly ahead of your class. The Biology in Focus book is only 400 Pages and isn't hard to summarise.
