I’d say it really does depend on your course and university. At mine, they generally like us to do group presentations in front of the class every so often (100 people) and we usually have tutorials 1-3 times a week where we are in small groups and talk about our work to each other.
To be honest, I reaaally dread them and hate public speaking, but i’ve somehow coped and i’m about to go into my 3rd year. Just try not to worry about it until the time comes, everyone’s in the same boat. Enjoy being a fresher, good luck at uni :)
