yes a good IELTS score per se does not make one eligible for KCL but yes if it's specified as a condition in your offer letter and that too a particular band score in each subset the admissions team will never budge and waive the requirement even if you have evidence to support the fact that you have done your entire education in English medium.In such a case clearing IELTS with the stipulated score as given in the offer letter is a big deal!

Anyways I have successfully achieved the conditions for my KCL offer and have secured an unconditional offer.

I second it. Even I secured 8 in IELTS nd 62% in grad got an offer from a host of places including UCL,Edinburgh and NYU but didnt get one from KCL as I was late in applying. However as I know that sippi has an conditional offer, its a matter of time to get that converted in to firm offer.

hey reet,
u said it i have already obtained an unconditional offer from kcl! :)
