I find them to be pretty good sections really because what they ask is straight forward. Like for the question what is an expert system all you have to write is
"An expert system is a decision support system that simulates the knowledge of a human expert to reach expert level decisions that would otherwise not be possible without an expert present. Utilizing a knowledge base, inference engine and database of facts to assist in the decision making process" - There you go... 2 marks in your HSC exam that easily. It's the weirdly worded communication systems questions that scare me
and yes, i have the feeling that this years paper is going to be hard.
