Question

When practicing for your oral presentation, you should do all of the following except: Hold any notes or index cards low and below your waist. Speak very quickly to complete the presentation in a short time. Practice your presentation on your own or in front of a mirror. Practice your presentation in front of friends or family.

Answer 1

You don't want to speak very quickly, you want people to understand you. You shouldn't hold your cards at your waist either because your voice won't project to the class. It's best to practice in front of people to get used to it. 

Answer 2

Hold any notes or index cards low and below your waist.

Speak very quickly to complete the presentation in a short time.

Step-by-step explanation:

When practicing for an oral presentation, it is best to practice in front of the people you are already familiar with, and who will give you valuable and sincere feedback. Families and friends will not shy away from giving you genuine feedback about your performance. Also, practicing in front of the mirror by oneself is also helpful, for it shows you how you are actually doing the presentation, and also reveals the things you need to change. You become the critic of yourself. Holding of index cards below the waist is also another thing to be avoided. Keep them above the waist, but not too high that they block your face. And, speaking fast is never a good thing while presenting anything. You want your audience to understand and know the things you speak of, not want them scrambling with the words you're throwing out in a rush, like a bullet train.
