Lesson 1
Critical Path Revision
Activate Year 11 network scheduling foundations: read precedence tables, identify predecessor relationships, sequence activities, and calculate simple path totals — preparation for earliest start, float and critical path analysis.
Lesson 2
Critical Path Analysis
Use activity tables to find earliest times, critical paths, project completion time, float, and delay effects.
Lesson 3
Gantt Charts and Dummy Activities
Construct Gantt charts from network diagrams, identify the critical path on a Gantt chart, and use dummy activities to model shared precedence constraints.
Lesson 4
Networks Exam Practice
Practise mixed HSC-style network questions involving routes, connectors, project schedules, and practical decisions.
