Low UCAT score but good A levels for medicine

If I scored 2550 on the UCAT but got an A* and 2 A's in A-levels (predicted), what are my chances of being able to enter universities such as University of Aberdeen and Glasgow? I heard that the UCAT requirements are high and am worried that I won't be able to make it into these universities. It's been worrying me a lot lately and would really appreciate some clarification.
