Do not give one word ‘Yes’ or ‘No’ answers. Instead, elaborate your answers when responding.
Don’t stop after saying something general. Remember the 5Ws and 1H (who, what, when, where, why & how) to help you elaborate.
Carry on your conversation with the examiner until he/she asks you to stop. When you close your conversation, remember to go back to the topic in your conclusion (e.g. Singapore will be a more gracious society and a happier place in which to live if we are all kind to the elderly. After all, we will all grow old one day too!).
