unfortunately you have left it pretty late. That's why the advice is always do your UKCAT in the first week or so to consider options.
Without knowing anything about you it's harder to advise.
Eg what degree do you have? What grade? What A-Levels (including grade)
You've missed the last entry for GAMSAT. That only leaves the BMAT, which I believe opens up the Oxford and Imperial grad degrees. But do you meet the rest of the requirements? Have you got time to prep?
You may instead want to try next year when you have planned and prepared your application and approach?
