It is hard to do any oral presentation, specially when I dont practice or prepared myself for it. I believe that the best thing that I can do for next time, is to give myself more time to prapare and not wait last minute to practice.  Also it is important to take the time to do any research and have enough information. I think having a plan writing and write all my ideas down, can help me. Practicing the presentation a couple of times, can help me not to speak fast and feel so nervous when it comes to public speaking.
