The job of a President is, of course, being the leader of the society. This includes delegation of work and projects, being in charge of meetings and being the representative to the student guild. You’ll be supporting everyone in their roles and make sure the workload is spread evenly; this includes organisation of the society as a whole and not just events. When making significant society decisions, if there is a tied vote or no consensus, it will be up to you to make the final call with all factors in mind.
