Can I study for a degree in Economics as a single subject at Oxford?
No. Oxford does not offer a single honours undergraduate degree in Economics.
How much Maths is there in the Economics part of the degree?
To a large extent, mathematics is the language in which much of university-level Economics is written and expressed. Introductory Economics in the first year uses elementary real analysis and differential calculus. Some subsequent options courses use more advanced mathematics and statistics while others use very little.
Do I need a Maths A-Level or other equivalent Maths qualification?
No, though you will find it helpful. If you are admitted without A-Level Maths, or other equivalent level qualification, the Economics Department runs a top-up course called Elementary Mathematical Methods which will bring you up to the level you will need.
If I study a joint degree like this will be qualified and able to pursue a higher degree in Economics afterwards?
Yes. Provided you select some of the more technical options papers in the third year (for example Econometrics, Game Theory. Microeconomic Analysis) you will have no problem at all accessing the very best Masters
