🧭 Exam Board & Specification

Eduqas GCSE Electronics. Assessment: written papers on electronic principles and systems (components, analogue and digital circuits, logic, programming of microcontrollers) plus a substantial design-and-build NEA — confirm the current weighting in the specification. These pages cover the theory papers' content; the NEA needs circuit simulation and prototype evidence on top.

🎯 Coursework & NEA Guide

How it is assessed (Eduqas): written papers on electronic principles and systems plus a design-and-build NEA (confirm the current weighting) — typically a product combining an electronics subsystem with an enclosure.

Your NEA frame:

  • Analysis of the design context → measurable specification
  • Circuit design: block diagram first, then full schematic with component values calculated (resistor maths for transistor/LED stages earns method marks)
  • Simulation evidence (e.g. circuit-simulator screenshots) for each subsystem BEFORE building
  • Prototyping log: breadboard photos, faults found and fixed (this is the iteration evidence)
  • PCB/manufacture plan + enclosure design with materials justification
  • Testing table: each specification point tested against measured results (voltages, timings), then evaluation

Top pitfalls: building before simulating (faults become untraceable); no measured test results ('it works' scores nothing); enclosure designed as an afterthought.
