Are you thinking of an aspirational university or a somewhat less competitive option?
If the former, are your grades/predicted grades in the right ball park for UCL, LSE, KCL, and/or QMUL?
If the latter, have you looked at Birmingham and Liverpool? How about Glasgow?
Have you taken the LNAT? If not, you might wish to book an LNAT slot if it's not too late to do so.
Good luck!
