University Guide for Computer science

Hey, I'm in year 13 and have to apply to a university very soon. Currently, I'm doing two A levels in math and business and one BTEC level 3 in computing, which is equivalent to one A level. My predicted grades are either AAB or ABB. But sometimes I think, What if I get a BBB? So I also have to select a university with quite low grades, which is BBB. Could someone please suggest a good university for computer science with a grade of BBB? Thank you!😃
