I am afraid Cleopatrai is mistaken about Leeds. For 2019 entry, the cut off to get an interview was 37/40 so somebody with perfect academics still needed 2/5 for BMAT.
The Leeds system is to score out of:
27 points for GCSEs or AS levels,
8 points for A levels and
5 points for BMAT
The GCSEs are 3 for an A*, 2 for A, 1 for B, including sciences, English Lang and Maths. Alternatively you can get 27/27 if you have 3 As at AS level.
A level - get 8/8 for AAA predicted/achieved, not worth considering applying without AAA; although technically you can, you lose too many points.
BMAT - they band the scores of the applicants and top 20% get 5/5, next 20% 4/5 etc. Last year 5,5,3A was enough for 5/5. They will not disclose exactly how they calculate the score, but they have told people that they do not score the letter in the section 3 score and that S1 and S2 have twice the weighting of S3.
This year there will be many more people with perfect academic scores as there are a lot of 8/9s around compared to A*s, so I would be amazed if the cut off went down, and not surprised if it went up to 38.
It can't really go higher than 38 because only 40% can score 4 or 5 for BMAT unless that 40% with 4/5 also have perfect academics, they have to interview at least some people with a score of 38.
(Last year there were 2,500 applicants and 1,000 interviewed, so 40%)
