Develop a test for 20 marks in your area of specialization (natural science).

The test must have 5 gradable items minimum (5 items/questions minimum that can be graded in the test). The items should have at least three different types of test items.
Develop an assessment tool (memoradum) for the test.

Remember that this should be like a test you would give learners in a school.
