Reapplying to the same Cambridge College?

The title is pretty self explanatory.
I got an offer from a college for maths last year, but missed the STEP grades needed. I'm reapplying to Cambridge this year, but for economics as I realised maths wasn't the course for me. In the process of choosing a college to apply to, I've been drawn towards the one I applied to last year (in terms of interview style, econ cohort numbers etc) ,so was wondering if anyone had advice on the matter.
Everyone and everywhere has the same opinion on reapplications, which is to apply to a different college than what you previously applied to. The only reason I've seen people give for this is that if you apply to a college you got rejected from, there was clearly something about your application the DoS/ admissions tutors didn't like - applying to a different college means differnt perceptions on that aspect on your application. In my case, (not saying there wasn't; anything in my application they didn't like!) but they obviously liked me enough to give me an offer, so what are the cons? Also since I'm applying for a different course, there's no chance of my interviewers recognising me. Opinions? Anything would help, I don't want to risk my place just because of college choice!

Hiya. Im in a similar position (had an offer last year but missed my grades and is now reapplying). Last year I applied to Newnham and then was pooled after interview to Robinson. Once I found out I had missed my offer (A*AA - but I got AAA), I got in contact with both colleges to ask about reapplying.
Both said that it was unwise to reapply there because both had recently seen my application and might be able to recognise it. They said that despite destroying all records of past applications, it could not help the fact that the admissions tutors might remember my application from last year and outright decline me because they know that I was unsuccessful before. For this reason I have decided to apply to a new college completely because it isn’t worth the risk.
In your case, I would check the fellows at the college you’re applying to and see if any are shared Economics and Mathematics teachers. If so, then I don’t think it’s worth the risk, as some of them might remember you and jeopardise your application.
I hope this is helpful and hope it goes well for you!
