FIRST OFF, it's definitely possible to still get 60+ at this time so remember that.
English: I really don't know how to study this so take my words as a grain of salt, I only chose a couple of adaptable quotes and explored ideas through that all the time. (Quotes that I can bring out an emotional aspect is my favourite.) But really, just don't forget about this subject like a lot of people do. Write a lot and you'll probably eventually get the hang of how to structure your sentences elegantly and you might get more skilled in adapting quotes for different topics.
Further math: CHECKPOINTS OMGG, really, they have solutions of PAST EXAM QUESTIONS in there. If you spend like even 40 min each week on those qs you probably will improve drastically as with Further practise and knowledge build-up comes from questions.
Accounting: never did this subject so I have no idea but someone at uni told me that it's all about practice too.
Studio arts: Got a decent study score on this, my advice is to cover all the components in the criteria sheet when you're doing the evaluation. That's it, you really don't need to write a lot but not very little as well (i took it as a personal competition to bs as much as i can and i bet my record of the most pages word doc i've made haha, someone from the year before mine who got 45 though, did about 1.5 page for each of her artworks). Just remember to make it
substantial.
Viscomm: realllllyyyy don't know, so I cant help!
edit:
She literally hates me and my friends in the class. Half of the class she hates, the other she loves.
Positive your teacher isn't as immature as to marking the class based on how much she likes them. She needs reasons to back up her marks.
You are in year 12 now, time to work hard and not laze around like snorlax. Be strong enough to persevere.
