I have an undergrad in economics from the UK (first class honours) -an OK school, not top 5 though- and a master's in applied economics from a good US university (GPA: 3.89/4). I am planning to apply to Oxford and Cambridge for their Mphil (prior to pursuing a Phd). I read on their website that if you have a UK degree, submitting GRE scores is not compulsory. Thing is, my GRE is about 4 years old and not so stellar (I have grown a lot ever since) and even though I am planning to retake it, I may not succeed in doing so before the deadlines. Should I still submit my old, not-too-attractive scores or should I submit no scores? I wonder whether no scores (as they are not compulsory in my case) may be wiser in my situation. Any thoughts?
