Should I take a risk?

So I currently have 4/5 offers on my UCAS for computer science and am very happy with them, King's was my aspirational choice throughout year 12 but my AS grades left my predicted grades short. Their requirements are AAB and I'm predicted BBB, but have received offers from Surrey and Queen Mary who ask for ABB, who I understand are more lenient but still. I have nothing to lose here, but was just asking whether it's worth substituting my last choice (UEA) for King's. Thanks.
