Evaluation of HSC 2015 Maths Exam - Prelim versus HSC Content

I took a look at the HSC 2015 Math paper and concluded that about 1/3 is Prelim, and 2/3 is HSC.

The Prelim questions are easier in general than those with HSC content.
Strategy wise, I think it would be good to get the Prelim questions 100% correct! so it's a good idea to ensure proficiency in all the preliminary topics.
Holidays are a good time to do that sort of thing.
Here are the BOSTES syllabus topics. 
We have essentially finished the preliminary content.

Here is my break down of Prelim/HSC content for those interested :-)

Merry Christmas, Happy New Year, and Fantastic Festive Season to everyone. 

Regards, :-) JH
