Well, it seems like Board of Studies are now letting schools access the raw marks for externals of their students (of course, note they have pretty much always had access to the aligned external marks of their students, but not raw marks...)
As a result, for the 2013 HSC, a teacher has let us know the following raw marks were adjusted to these aligned marks as below. By the way, rep will be appreciated for this valuable info
EXTENSION 2 MATHS (4U) - NB: Actual exam was out of 100.
60% (raw) --> 87% (aligned)
65% (raw) --> 90% (aligned)
70% (raw) --> 92% (aligned)
75% (raw) --> 93% (aligned)
80% (raw) --> 94% (aligned)
86% (raw) --> 96% (aligned)
90% (raw) --> 97% (aligned)
93% (raw) --> 98% (aligned)
EXTENSION 1 MATHS (3U) - NB: Actual exam was out of 70.
64% (raw) --> 88% (aligned)
67% (raw) --> 90% (aligned)
70% (raw) --> 91% (aligned)
76% (raw) --> 92% (aligned)
92% (raw) --> 97% (aligned)
99% (raw) --> 100% (aligned)
Okay, cool! Hope that provides some insight. Esp with it being stats from last year...
