Thankyou for all the info and support here. DS is feeling fine today. Basically, he was very borderline about applying for Geography or HSPS at Cambridge. He went for Geog as he hadn’t taken Politics or Sociology A-level, so thought he might struggle with HSPS against those who had. But he very much a human geographer and actually, it was the LSE course that initially inspired him. He went for C as he had the grades to apply - that’s it really. At UCL and LSE it’s all Human Geog (apart from a climate change module but obviously that’s one of the biggest challenges for his generation and feeds into everything). Particularly at LSE, you can take modules across the social sciences. A language module is encouraged too and if you proceed on this pathway you come out with that language as a ‘with’ for any BA / BSc.
DS has really enjoyed Economics but couldn’t proceed with it to degree level as he didn’t take maths A-level. This is one of the setbacks of his type of independent selective school. He was in one of the bottom maths sets (like set 8 out of 10) so always perceived maths as ‘not his thing’ throughout school. Even though he ended up in the 60% or so in his year who came out with a 9 at GCSE, he still thinks he’s crap at maths and was never offered the further maths GCSE option because if the maths set he was in. Anyway, at LSE particularly, there is a large overlap between Geography and Economics (as well as Anthropology, Politics and across the social sciences really) - and this intersection is really his thing. He can take modules from other departments and this is encouraged. He’s not the green wellies type, put it that way.
Interestingly, at C, of the 4 interviewers he saw, 3 were glaciologists and on was an oceanographer. Hmmm.... The entire first interview was about glaciers (even though I’d been assured interviewers are not supposed to only ask questions related to their specific research areas - that’s precisely what they did).
Also, at all his other uni choices there is the option of an overseas year. After this, if he still feels he wants to go to Oxbridge, he can apply for a masters anyway. So basically, he’s realised it’s all just a different route to wherever he’s heading and I know it will be the case for all the DC here.
