For 2015 applicants
Example : Predicted A*A* A (400tariff) , say you also have 2 additional AS subjects at grade a (60+60 tariff) , a distinction in a music exam grade8 gives 80 tariff . So your sub total becomes 600.
Lets say you have scored 2660 in the UKCAT (2660/4 = 665 points)
Your total score becomes 600+665 =1265 points
In 2013 threads, the cut off was around 1300. Unless Queen Mary changes their calculation method this year and noting that mean UKCAT scores have come down by around 40-45 points, I suspect (as an independent observer) anyone scoring above 1250 points will have a pretty good chance of getting an interview.
