Hi! There are two modules one in the first term that's maths based, differentiation, algebra etc, you can take the harder route if you want which has matrices and harder differentiation in or the easier route and still end up with a BSc so id recommend that.
The second term is statistics or econometrics (the harder route) but the main difference is the easier route is more applied whilst the harder focuses on the theory. The main topics in the stats route are hypothesis testing, using normal binomial and Poisson distribution and regression.
There are essays you have to do of course, you do many modules each term, some can be outside of the economics school but you get given essays to complete during the term which are worth doing as they're similar to what comes up in the exam.
I did both maths and economics A level, the core micro and macro topics aren't too similar to economics a level to be honest, macro at nottingham is quite in depth looking at macroeconomic models, there are ALOT of different graphs to learn, I would reccomend for micro reading one of the books over the summer it will help a lot. Go on amazon and buy the first micro book it says to buy if you look online at the course then click on micro!
I did all of this and managed to get a 1st in the first year, I got my results yesterday!
After Uni I want to get into investment banking, very interesting and also the pay is ridiculous haha! Any more questions?
