Answer :
Malcolm, being good at math and able to do most calculations in his head, should remember the following when taking math tests:
C. Show his work so he doesn't get points taken off.
By showing his work, Malcolm can demonstrate his thought process and how he arrived at the final answer. This not only helps him double-check his work for accuracy but also allows the teacher to see the steps he took to solve the problem. Showing work is essential because even if the final answer is incorrect, partial credit can be given for the correct steps shown.
In addition to showing his work, Malcolm could also consider:
D. Preview the test when he first receives it.
By quickly previewing the test, Malcolm can get an idea of the types of questions asked, the point values assigned to each question, and manage his time effectively during the test. Previewing the test helps him plan his approach, identify easier questions to tackle first, and allocate time appropriately to each section.
