I’m a lecturer so this is my job, but sometimes I still feel really nervous, especially with a new group of students! I also have students present to me, and these are my top tips for them:
Do a trial run and time yourself in front of a mirror - if you need to speak for eg 15 minutes, aim to talk for about 17 minutes in the test, because you will speed up if you are nervous
Wear something that makes you feel absolutely fabulous - even if it is lovely perfume
Use flash cards if you have to - I tell students to keep text on slides to a minimum and have postcards with notes if that helps
Rescue Remedy drops on your tongue, or rubbing some lavender oil round your nose really helps
Have a “reward” lined up for afterwards. Coffee and cake in a nice cafe, something really tasty for dinner, buying a bunch of flowers on the way home, ordering that thing you really fancy online
I don’t say this to students, but I know it is true - a lot of people won’t really listen to or remember anything about what you say. They will be thinking about what they are having for lunch, the hot guy they met at the weekend, whether their DC has their swimming kit in their school bag, or what is going to happen in that evening’s Corrie.
Prior to being a lecturer I worked in TV (not on camera) and there was a saying “it’s only TV, no-one actually died” when stuff went wrong on a live. This is the same. I sat in an online training the other day where the trainer’s washing machine was so loud no-one could hear him. My cat has joined numerous live remote lectures either by squawking at birds outside the window, or scrambling onto my lap. No-one expects things to be perfect!
