Another option could be just practicing while driving in your car. It sounds weird, but think of questions you'll likely be asked and try to answer them. I also suggest this kind of practice for job interviews. It also helps even if you are a good conversationalist, because it helps you 'own' your answers and still sound natural and not rush your speech when the question is asked. It's worked for me while practicing for the other side of recruitment as well as for job interviews. Best of luck!
