It's just odd that they would accept less qualifications, and also UCL is odd in the sense that I'm pretty sure its the only one that reads more about like PS, GCSE in arts, etc than other medical schools.
Also, I didn't meant for Oxbridge as a benchmark, more as in their requirements for things are generally higher (eg. requiring A*A*A), and not accepting many types of qualifications alone, so it is quite odd that UCL is stricter than Oxbridge in the qualifications regard.
