Cambridge HSPS application

Hiya! I'm currently on my second draft of my personal statement, I am applying for Politics and International Relations elsewhere but HSPS at Cambridge as it is the closest thing they have. Obviously HSPS entails politics and International Relations but should I aim to include the other subjects too? even if its only briefly? or will they understand and think its enough? I can easily bring in some anthropology but I don't want to waste words if I don't HAVE to and it will look a bit funny for the other unis. thanks

Assuming Cambridge is your top choice, I would add at least a couple of lines regarding anthropology. It is such a competitive course that it is best to do super curriculars in all aspects of the course to strengthen your application. Can’t see it being an issue for other unis.

okay! if my subjects have elements of sociology in them for example, could I get away with having a teacher reference that showcases my interest for it or does it have to be in my personal statement? like English Language has bits of sociology in it

From what I’ve seen and read, the general attitude from Cambridge academics seems to be that you should focus on them in your PS, as they are number 1, and the other unis will understand. Personally I therefore think it’s best to include your PS.

This is wrong - Cambridge advises writing the PS for the other choices as they have the additional PS section to talk about why the course at Cambridge.

They say that on the web, but on a live chat, a DoS from one of the large colleges, said that you should focus on Cambridge in your PS and that other unis would understand. Maybe attitudes between DoS varies, but if your primary focus is on getting into Cambridge, it can’t hurt to gear PS towards the Cambridge course.

Considering the PS forms a smaller part of the overall application than for most other universities it would be foolish to tailor it to Cambridge specifically. Those other universities are likely not to be working with anything beyond the UCAS form and competitive unis like LSE can and have rejected people on the PS.
Considering the DoS also doesn't have final say (that would be the Admissions Tutor in conjunction with the DoS) I'd take that one time with in a webinar with a pinch of salt. I've worked in and around colleges over a number of years now and assure you and OP tailoring PS to just Cambridge is a bad idea, unless they're not applying to any other UK uni.

I agree that other unis typically have less to go on than Cambridge, and that for unis such as LSE, the PS is extremely important. You are still left with he dilemma though, that if you gear your PS towards the Cambridge course, you potentially increase your chances of getting in to Cambridge, but potentially reduce your chances of getting in elsewhere, depending on how competitive those other courses are.
My daughter had the same dilemma for Land Economy this year, but decided to go for it and focus on Land Economy in her PS and it paid off. That's a sample of one though, so feel free to ignore. It's up to the OP.
