### Assessment

#### Assessment Strategy

Weekly problem sheets provide formative feedback. Technical labs are conducted under the umbrella of ELEC1029 but the marks contribute towards this module. Skills labs are conducted under the umbrella of the zero-credit ELEC1029 module and address its learning outcomes. The marks contribute to a number of ELEC12xx modules, including this one.
