They're all 3As, I felt like applying to one with A*AA would be a bit too risky for my liking.
My main concern is Queen Mary, looking at these stats for last year:
Top and Bottom examples:
Low Tariff of 152 supported by a high UKCAT of 2,290
High Tariff of 330 supporting a low UKCAT of 1,760
Mid-range examples:
Tariff 300 UKCAT 1,870
Tariff 282 UKCAT 1,960
Tariff 216 UKCAT 2,120
Tariff 196 UKCAT 2,240
Tariff of 196, about 32 higher than mines had a UKCAT score of 2240, avg 746.6, so he/she had higher tariff, aswell as higher UKCAT avg - if these are representative of the average offer than man i feel really worried
