Graphs, paths, minimum spanning trees and critical path analysis, where the answer is a structure or a schedule rather than a number.
These are the statements the Mathematics Standard 2 syllabus makes about Strand: Networks. 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.
Vertices, edges, degree and paths, and the vocabulary that makes a network question answerable. A diagram is data, not decoration.
Activity networks, earliest and latest start times, and the critical path, which is the sequence that determines the whole project's duration.
Shortest paths and minimum spanning trees, and the distinction between a route that is legal and one that is optimal.
Using vertex degree to decide whether a network can be traversed without repeating an edge, and explaining the decision from the degrees.
Modelling dependencies in a project network, including when a dummy activity is needed to keep the precedence correct.
HSC Mathematics Standard 2 - Trial Paper Shape is 100 marks in 150 minutes. Questions on Strand: Networks 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 Mathematics Standard 2 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.
Strand: Networks is module 5 of 6 in Mathematics Standard 2. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Mathematics Standard 2 dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
