Having researched how the programme of such a degree typically works in the UK, I personally feel very enthusiastic about the thought of being able to combine two, maybe three, of my interests academically. These programmes seem to be well organised and do appear to allow you to pursue the major/minor route, or study perhaps two subjects in significant depth, a level of depth comparable to that which a joint degree provides, which appeals to me.
However, because it's relatively new to the UK, I am concerned that employers and those in academia who have studied a traditional subject will view this as a 'pick and mix' degree, even if it has been obtained from a Russell Group. I intend to major in a science subject and acquire the skills, knowledge, etc to the level of someone who has done as straight degree (Lib Arts/Sciences will provide that due to an extra year at uni) but I wouldn't know how I would demonstrate that to employers put off by the degree title. Equally, would I be disadvantaged applying for internships? Would I be disadvantaged if I wanted to pursue postgrad study/go into academia? When I spoke to staff at a uni I'm interested in about my possible commitment to majoring in a subject/taking the modules that would give me a foundation for doing a Masters through this programme, they just talked about the flexibility of my programme and how I shouldn't worry because of this... and I've heard that at UCL (don't quote me on this, and do correct me if I'm wrong) that Liberal Arts and Sciences isn't too respected by the other departments.
I can see that studying a couple of different disciplines would be, in practice, demanding, and the entry requirements seem to reflect that: A*AA - AAA at UCL/Birmingham/Durham/Bristol. It's not a "drinker's degree", but will it be seen by employers/the world of academia as such?
Should I be worried about the prestige of the degree?
