People will ignore your information if not presented in an appropriate manner.
DON’T try to “juggle” too many points at once. State your ideas in a logical order.
TIP: the more you practice and plan your speaking, the less nervous you will be.
Remember: Any argument that you do not address in a rebuttal will be left in the memory of others as your opponents stated it. Likewise, any rebuttal from your opponents that you do not address will also be left in the minds of your audience / judges.
