Hi, I'll answer both questions in a 2 part reply.
Firstly, yes it is possible to get a high mark despite having a mediocre prelim or internal mark. For example, I took Studies of Religion I (I was forced to since its mandatory at my Christian school). TBH, I despised the subject and did not plan on including it in my HSC, thus I often left studying until the weeks leading up to the exams. I ended up getting an internal mark of 39/50 then 42/50 after trials. My rank was horrid. Probably around the 40th-50th percentile of my grade. I decided to put in some effort and got a 48 or 49/50 in the HSC exam which brought my total HSC mark to a 45/50 on the dot. Basically, my advice would be to not worry yourself too much about ranks and to focus on getting as high marks as you can. I've seen way too many people lose hope after seeing their ranks after an exam.
Secondly, I got a B6 in Eng Adv and 4U Eng so i might be able to help a bit. My Trial mark for ADV was abysmal (79/100) ;-; but my other internals and HSC were good enough to get me a B6. How I recovered? I pestered my teachers for feedback and i kept on writing essays, practice responses, ETA's etc. One thing I would strongly advise against is relying on memory/memorising base essay's. English is all abnout understanding the text and being able to adapt to the question. One way I did so was by getting past paper questions from THSC and either writing entire practice essays, writing bodies or just a mere thesis statement.
One thing that I think really helped me was this:
Sometimes writing an entire essay may seem a bit much right? Basically, I wrote numerous thesis statements answering different questions from multiple papers using various thematic concerns etc. You thesis statement is essentially the crux of your essay as it comes first and foremost and notifies the marker what you are talking about, how you will answer the question, and how you interpret its contents.
Here's some resources I used which helped significantly. I've thrown in some Mod A - Richard x LFR resources that I had on hand. If you want to share what modules you are doing I'd be happy to help.

When initially looking at the term ‘textual conversations,’ one can easily feel anxious. Yes- it may sound a bit convoluted and technical, however it really refers to the ways in which one text can create a dialogue- whether it be thematic, contextual, structural or paradigmatic- with another...
