Going into second year so here's some advice for first year.
Make sure to join societies as their a good way to make friends of similar interests.
Make sure to go to lectures and learn the material in the first year as all the further years will be based off that information.
Make sure that you don't worry too much about grades even though i said the point above in terms of final grade the first year doesn't impact that grade aka don't worry if you get a bad exam grade or something , your life isnt over lol.
Also make sure you go into a subject because it has both job prospects and also its something your passionate about.
