Asking how much ppl wrote is pretty much pointless unless u ask them everything else abot their writing...e.g. People have different sized writing, people write a whole booklet of irrelevant crap, people have spaced out writing...etc.
I wrote 12 pages for section 3, and 7 for section 4, and I've got average writing I guess, like 6-7 words per line, and some of my reports contained some bullshit, e.g. maybe half a page to a page of crap for each report. I think it was a sufficient amount, although would've liked a bit more for section 4, but ran out of time.
Btw....got my FIRST EVER STRING TODAY!!!! I was aiming for at least one string for biz, and I got it. I know how sad I am, shut up!! One string in the whole HSC yay!!
