Curriculum End Points

By the end of Year 11 students will competently be able to design and make a circuit and PCB which includes a range of subsystems which solves a problem for a given brief. Students will also be confident in being able to make more complex mathematical calculations which determine such things as Amplification, Frequency, Gain, timing ratios etc across a range of circuits. Students will be able to recognise how complex circuits can function by breaking them down into their subsystem elements and describe both the function of components in a circuit and how they impact on each other. Students will also have the capacity to edit, improve and evaluate existing circuits for a set purpose.
