turn it down if its not the place you want to go to! on my offer letter it said please can I let them know within 21 days if I decide not to accept the offer, becuase they might be able to offer someone else my place, so don't worry about you wasting a chance for someone else, its your lift so decide whats best for YOU.
Of course, if you'd not be comfortable there, then you ought not to go. Despite what people tell you, how well you do in your exams at Cambridge will determine your future, rather than merely having gotten in. If however you're ok with the prospect of being there for 3 years, and do not feel performance is likely to suffer...go.
Also bare in mind that some colleges and certain courses within Cambridge are a hell of a lot more valued by employers than others...As it happens, Econ. at Cambridge is very highly sought after, soo...you will be turning down a degree that's worth a great deal after graduation.
I think I'm correct in saying York is better than Durham for PPE.
hi my name is sarah and i was going ot apply to cambridge for economics too but i thought before hand.you would not have got urself in this pointless and completlely *(y are u discussing this wen u dont even have an offer yet)* dilemma if u hadnt applied.if u didnt want to go there u shudnt ve applied, and now that you have i think u shud just wait for thier reply cuz to be honest u probably wont get in js like all the really clever pupils they turn down every yearanyway, so mate my only advise is to CROSS THE BRIDGE WEN U COME TO IT! and dont assume things too soon cuz u might be dissapoointed. i dont mean to be harsh just tellin u the truth good luck with everything tho.btw i got an offer from nott too to study econ, mite c u there!
