You probably didn't learn about referencing at school, but it's about to become the bane of your life. Every time you use a statistic, quote, or use some kind of information or idea that isn't your own in an essay, you have to write down its source. Your seminar leaders or lecturers will talk you through the ins and outs of referencing at the start of the year, and it's probably one of the most important things you'll learn in your first year. It's definitely boring and sounds simple enough, but pay attention and write notes. Being proficient in referencing will save you hours and hours of time throughout your degree. Thank me later.
