The Higher Grade Physics course is composed of three units on Mechanics and Properties of Matter, Electricity and Electronics and Radiation and Matter. These units are 40 hour nits. Each unit is assessed by an end of unit test. The candidate must also complete a practical test for the course. If a candidate passes the test for a given unit he/she will be awarded a pass in that unit. Furthermore, if the candidate then passes the terminal Higher Grade Physics examination (which covers work from all three component units) he/she will be awarded an overall pass for the course at Grade A, B or C.
