I am in spanish 2 right now and if i was you i would have alot of information or like alot of sentences in spanish with many different forms of verbs and conjugations.
I am a native spanish speaker and i'm taking AP spanish right now. I would put as much information as you can on the powerpoint in spanish, also be sure you know how to say the words you need to say clearly and try to let your words flow. Hope this helps :)
