I don't always think that the admin staff are a reflection of the medical staff, but given KCLs student satisfaction and overall ranking I would say its pretty representative.
Medicine is the most competitive course in the uk. You will face not only a huge surge in applicants, but also a limited number of places due to the large volume of deferrals. In addition to this, you only get 4 choices - so choose wisely.
Kings has treated its med applicants horrendously and shown no regard for any of the hard work that you put into your UCAT, personal statement and work experience. The majority found out they were rejected from an auto reject by ucas because kings wouldn't reject us with dignity, only to be followed by a message from kings the day AFTER the ucas deadline saying to ignore this, finally to be followed by an official rejection straight after - even though they were aware that many of the applications would not be interviewed long before and instead decided to ignore the mental strain that the waiting for an inevitable rejection. Meanwhile, this is all happening during the IB exam period, and also right before the A level exam session too.
Don't waste one of your precious choices on a university who wont even recognise you as a human. If KCL is what you are really set on then so be it, but if your heart isn't 100% into kings I'd instead apply to a university that will treat you with respect
