Speaking and listening help!

Hey guys! I have a speaking and listening exam on Thursday and I'm actually quite struggling on it. I have to talk for 3-4 minutes (a speech) on something I am passionate about. I have a topic and I have a speech, but I can't seem to remember it 😖 I'm allowed a que card with notes but that doesn't seem to help 🙈 please can I have some advice! Thanks in advance :)
