Is it worth doing BA Economics?

I would look at the courses and what modules youll be taking. From looking at other BSC courses my Ba course has more maths modules in it and at the end of it i could have done far more maths than alot of Bsc student. So try not to look at it from a Ba vs Bsc standpoint. Look at unis you like then at the course.

It's not just about how many modules, but also what said modules contain. Taking Exeter for example, sure half of your modules can be maths/statistics in the first year, but this is only possible if you don't have A-Level Maths, otherwise it's three eighths, and also your Introduction to Statistics is quite basic, more than likely because there will be plenty of people without A-Level Maths or any statistics background, and what's with all the formulae you get with the exam?!

But yeah... It's not just about how many modules you're doing.

Yeah saying the amount of modules probably isnt the best way to look at it, ive also looked at the module breakdown and topics for some other unis doing Bsc and it doesnt seem like theres a big mathematical difference. And with the stats one, the content of the module isnt basic (well i dont think so) but they've dummed down the exam for some reason.

What wrong with the formula not seen Southampton's one but would you mind showing me an example of your stats and micro/macro exams..

You edited your post!! I want to see the pre-edit version!

To be honest, for most decent universities there isn't a major difference. It's only really Oxbridge/LSE/UCL/Warwick which have a much stronger pure maths element to their maths modules.
When I researched universities, the biggest difference I found was in the level of econometrics and also the difference between just techniques and actual mathematical theory.

Formulae are bad.
Nah, in all seriousness, I'm just surprised at how much formulae you guys are given, and how basic some of the formulae are, but again, it's going to be because many on your course won't have A-Level Maths and so will never have encountered statistics before (as a lot of that stuff isn't even provided in A-Level!).

Here's an example of our Semester 2 statistics module exam from 06/07:

Nothing much else is available online freely, but if you want I could always send you via email an example of our first semester stats and micro/macro.

I understand, especially further down the rankings you go, that the maths involved isn't too much different in a BA or BSc. However, that's not my problem, it's just getting on to a BSc course!

Also, how much of the maths involved is statistics? I'm assuming most of it. Is there any cases where the maths involved would be similar to that of core maths at A level?
