I think Ash and IceCrem are from VIC. In VCE, they use top 4 subjects + 10% of the next two subjects’ SSs to calculate your ATAR, but your English subject will be included in your Top 4 no matter how well you do (but if you do more than one English, then you will get the better score added).
In QLD, you use Top 5 subjects (English will only count if it actually is one of your top 5 subjects, unlike VCE).
Ash444 If it is only English you struggle with, I’d advise working on it and improving your grades by seeking help particularly on your essays and writing.
I wouldn’t change my career preference, but have a back up or two in case things fall through, but in the meantime, control what you can. Year 11 allows you to refine your writing skills so try to practise more and get feedback from your teacher while you have the opportunity. Good luck!
