Cami should record something that seems important to her and that goes along with her subject. Going off subject could make readers and listeners become bored and decide not to read or listen to it.

As an oral presentation is to reach to the audience and effectively communicating to them, Cami will have to record information about the topic, be precise and keep it interesting, don't record information that seems boring to you, as if the information doesn't fit with you it won't fit with the audience, what you present should be interesting to you as the audience may read through you. Record what feels right to you knowing you can deliver it to the audience.
