I was answering the SAQ questions and apparently there's a part which I can add Cambridge Specific Personal Statement and another section with the question "Is there anything else you would like us to know?". I did some research and saw a comment on Student Room by a college's AT:
"See my reply above about this, but it's absolutely not necessary to get an offer. I think about half of applicants fill it in but it's very rarely a significant part of their application. The best way to use it is if you are applying for various courses at different universities and Cambridge is different to the others (e.g. Nat Sci, HSPS, ASNC)."
"The SAQ personal statement is completely optional and many students leave it blank with no detrimental effect to their applications. We'd rather it was left blanck rather than filled with waffle, stuff from our own prospectus or repetition of your UCAS personal statement. It is most often used when the course you're applying for at Cambridge is different to your other UCAS choices so your UCAS statement doesn't quite match the Cambridge course. Examples might be if you're applying for Chemistry everywhere else but Natural Sciences at Cambridge."
Here are the courses I'm applying for:
History and Politics (Cambridge)
Politics and International Relations (UCL)
Politics and International Studies (Warwick)
As you can see, I'm not exactly applying for a course unique to Cambridge, nor to very different courses in other unis, and I also have a solid history section in my PS which is very well connected to politics section. So I don't have much to say in the SAQ Personal Statement. I don't have anything to add as additional information either. The problem is that I'm concerned about leaving both Additional PS and the other question I mentioned in the beginning blank would make them think that I didn't give enough attention to SAQ. What should I do?
