I don't think I'm going to be ranked very well in a particular subject, but in the exam I might do better than some people ranked higher than me. I'm at a very small school...will I get dragged down?
Um, which 'exam' are you talking about? Trials or HSC? There's really no scaling involved for Trials. As for HSC - it's your rank from your internals that is important.
it depends on how much better you do, i mean if your ranked say 25th but you're only 5 marks behind the person who's 3rd and you do really well then won't everything be fine?
