How information is transmitted, stored and secured, and what limits each medium.
These are the statements the Senior Science syllabus makes about Information and Communication. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.

Year 11 Course Examination Shape is 100 marks in 150 minutes. Questions on Information and Communication are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Senior Science uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Information and Communication is module 3 of 4 in Senior Science. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Senior Science dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
