College Signing Day Tips??

College Signing Day Tips?? Ok so as the title says, I need tips to reduce my chances to not embarrass myself in front of a huge crowd of parents and other schools. My school has been practicing for this day but like only 4 times and three of those times I stuttered. If I can’t simply say hi and my name and the school I’m going to in front of my classmates without stuttering then what makes me think I’m not gonna embarrass myself when the day comes? Like I didn’t even stutter in between the sentence only when I have to start it with “hi” I can’t even breath out the letter h. I need help. :(
