Phase 2: Learners develop the actual product or artefact at the start of the second term and finalise it by the end of term 3. Phase 3: Learners submit the product or artefact for assessment by the end of the third term. The accompanying planning done in phase 1 (design portfolio) must also be submitted for assessment at this time. Examinations The mid-year and year-end examinations for Grades 10 and 11 should consist of one paper which counts 200 marks. The suggested duration of the paper is three hours. All the questions must be compulsory. The questions should be set in such a way that they cover the knowledge and skills of Learning Outcome 3, the investigative assessment standard of Learning Outcome 2, and the values and attitudes of Learning Outcome 1 of the Electrical Technology Subject Statement. The format must be similar to that outlined for Grade 12.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
