 1. Short Answers It's a huge misconception that in visa interviews you need to speak really less and you need to give short sentence or one line answers. Now for questions like why this course unless you explain yourself to the visa officer there is no way he is going to be convinced or understand your profile. So do not pressurize yourself to give short one word answers or one line answers. Why this course answer needs to be descriptive you need to explain yourself to the visa officer and this answer should be at least three to four lines. What is required here is that you practice this really well so that when you speak you are able to speak quickly fluently and finish your answer before the visa officer interrupts you.
