hello
i just got accepted for a teaching job, im only going to be a sub so its not really a lot of teaching but im terrified at the idea of standing up in front of a class full of kids even and talking even if its just 2 lines. people have told me that it gets better the more i do it but ive taken a public speaking class before and i didn't improve at all. doesn't help that my native language isnt english either. i also tend to like mentally black out when im giving presentations and stuff so i have no memory of it when im done and the only way i know how i did was with the grades i get (which are not good, the best ive gotten is a B i think)   any advice ??
