How mathsy is the course? What kind of maths do you encounter? Calculus, logs etc
Maths is only really used in the first year first semester (Mathematical economics - i.e. matrices, calculus etc). The rest of the quantitative stuff on the course is statistics. You can take advanced mathematical economics in year 3 last semester if you want, but statistics is far more useful in economics than maths ever has been!
How did you improve your economics essays to A grade standard? What structure did you use?
My tip would be to just write in a very punchy manner. Economics A-level for me was difficult to get a good mark because the essays were actually easy but very broad, so I just improved my writing style. Weird tip I know, but it worked!
