Really nervous about presenting project in front of cl.?

On Thursday everyone has to get in front of the cl and have memorized a poem AND act it out a little from Macbeth. I get really nervous in front of the cl. Mainly because they are all the "popular" people who i never really talk to and i just don't want to look stupid. When i do present things i get really red in the face and my hands start to shake and my voice too. I don't know how to come over this fear!
