Hmm it really depends how hard they make it...i want it be like the first set of Specimen Papers as they were soooo much easier...the second set are an absolute bitch....so hard! If i got them in the exam, i'd surely fail.
But to answer your question, my teacher said he doesn't think they'll change that much...about 78% for an A which equates to 62/70 i think...but i'm not sure i feel it will be a low lower...i kind of just want a B or a C in Chem this year. B maybe like 68% and C 58% roughly..What do you think the grade boundaries will be like?
