What are people’s thoughts on double degrees -eg Maths with Geography etc

Lots of my friends have joint honours degrees, possibly because we met at a university whose philosophy centred around the notion of producing graduates who experience 'an interdisciplinary curriculum'. The only ones who don't have joint honours are those who studied International Relations or Physiotherapy. The rest of us studied all sorts of combinations from American Studies and Biology to Geology and Music.

I'm so glad I did a joint honours degree as it opened doors I didn't know were there to be opened; my research career would have been unlikely to have existed had it not been for the second of my subjects and I loved being able to pick units from the two subjects that overlapped in a roundabout sort of way. Studying one interest subject and one National Curriculum subject has meant a number of friends have been able to go into teaching on the back of their NC subject which would have been rather more complicated if they'd only studied Psychology, American Studies or Criminology for example.

If there are two very different subjects your DD is interested in, I'd encourage her to look at a joint honours degree, especially if they're subjects that are unlikely to be pursued via amateur/extra-curricular involvement.

Do you mean a joint degree or a double degree?
A joint degree is taking 2 subjects, half each. I did that and it has never been a problem. In fact, it have me a second subject to teach. If she wants to go into a career that needs specialism then it's a bad idea.
A double degree is taking two full degrees at the same time and is pretty unusual. You have to find a university that structures classes so that it's possible, and recognizes double degrees.

I contemplated doing a joint honours but I’m glad I didn’t as on my course all the core subjects were the harder/less interesting ones. I presume it’s similar on the other course so I would have found myself doing a more intense and less enjoyable course. The core topics were ones everyone had to do.

I did one and rather regretted it as I realised I loved one subject and not the other. Beyond university - nobody cares!

I did a combined degree. So, a selection of modules all from social science departments. You don't do less depth as such because each module you cover is the same degree of difficulty as someone else who does a degree with a single subject. What you get is less breadth. For example, you may do politics and only do modules on international relations or America. If you plan well the degree will have links between the topics that add value. The links can add an extra layer of understanding that improves your analysis of both subjects.

Apologies for the typos but you get my drift!

I've got one, it was helpful for broadening career choices and seen as higher status for covering more than half of each subject. That was a million years ago though, no idea whether they'd still be seen the same way!

Do you mean a joint honours degree? They do vary - dome will be 50/50 and others will be a minor/major.
The key is the combination - it obviously works better if they are complimentary subjects and from a practical pint of view it helps if the two subjects are based in the same faculty or school. As an academic and a career guidance professional I really wouldn't recommend doing two very different subjects. They don't work very well in my experience.

From an employers point of view it's often useful to know that 70% of graduate employers don't ask for a particular degree subject.

She would probably benefit from speaking to a qualified careers adviser.

I’m wondering this too but I think you’d be better moving it to ‘Higher Education’ if your talking about university degrees.
