Teacher's are only pedantic about the wording of answers, because that's exactly how it is in the hsc exam!!!
In our trial, I knew about 95% of the material, and I knew exactly what I was talking about in my answers, but because I didn't use the words required in the marking guidelines, my mark was umm...68% I think....
That's exactly why the comments from last year's markers include:
"students can benefit by more precise and scientific use of terminonogy, especially that specified in the syllabus"
I dunno about you guys, but tonight I'm learning my terminology!!
GOOD LUCK to you all!!
Remember, it's not worth stressing about!! The more relaxed you are, the more you remember.
