I got 86 (HSC mark) for Standard English. It's not that hard people! Just know your techniques and effects for all your texts really well. I chose Standard because Advanced English doesn't scale up, and I'm not the biggest fan of Shakespeare.
Band 5 in Standard English is totally achieveable! All you need to do is ANALYSE critically, don't go into story-telling mode because markers don't even care about the plot. Select your related material wisely for your Area of study and your modules A and C.
Get yourself a tutor to check your all essays and creative pieces (for paper 1, section 2) and you'll do just fine.
