(MORSE is a course at Warwick focused on the applications of maths, involving Maths, Operational Research, Statistics (quite a lot), and Economics
Edit after some more research: They are very similar courses and you can cover essentially all of the same topics with either by choosing optional modules, except at Oxford you cannot do the economics stuff because the department is separate. The other difference is compulsory modules. MORSE has a lot of stats, whereas in Oxford Maths+Stats there’s stuff like Geometry, Dynamics, and Complex Analysis.
I would be capable at and interested in either one, so it comes down to which sets me up better to do good (I'm interested in a wide range of things so keeping options open is important for me)
It seems to me that its greater and broader focus on application, with less pure maths, gives you more skills for impactful paths without much trade-off, but I'm not very confident that I'm accurate in this judgement since I have very little understanding of the world of employment.
If it is better, I'm also wondering how the benefits would trade off with the higher prestige of doing Maths+Stats at Oxford, but I don't have any idea how big/small the benefits of either side are. What do you think?
Thanks so much for your help!
