Overview of Assessment

This is a progressive assessment, the students are required to undertake summative assessments as follows:
A. Practical laboratories
B. Written reports for the laboratories
C. Written assessment


Assessment Tasks

This is a progressive assessment consisting of the following:
Assessment task 1 (Practical Exercises): 30%
Practical Laboratories: The students will have to complete minimum of three laboratories as specified by the teacher for the practical exercises and demonstrate the understanding of amplifier fundamentals through the developed project.
Project Modules: The students will design and develop the project module(s) as specified by the teacher for the practical exercises and demonstrate the understanding of amplifier fundamentals through the developed project.

Assessment task 2 (Written Assessment)
Written Reports for the Laboratories and Project Modules :10%
Written technical report as per the requirement and specifications for each of the project modules should be submitted by each student individually. 

Assessment task 3
Centralised exam: 60%
The students will have written exam to demonstrate their theoretical knowledge based on basic amplifier circuits as detailed in the course.

CHD- Competent with High Distinction
CDI- Competent with Distinction
CC- Competent with Credit
CAG- Competency Achieved - Graded
NYC- Not Yet Competent
DNS- Did Not Submit for Assessment. (This grade is only to be used where the student’s attendance in the course has been ‘confirmed’ (but they have not participated in any form of assessment and did not withdraw by the census date.)
