I am a lawyer in Brazil. (Third world country)
I did not have IELTS score.
I applied for a post-graduate program (Paralegal).
And I received AIP.
So... you don’t need to apply for a Master.
Maybe your letter was not quite so good.
I said that the most important thing at this course was the network. As a lawyer, it would increase the numbers of clients that my office already has.
Ask for GCMS and try again.
Good luck.
I am a lawyer in Brazil too.I have three post-graduations in Brazil.
I applied to Bachelor's degree, mayor in Criminology.
I've received AIP last August.
I consider my letter was well written and it helped to pass eligibility.
I received GCMS notes 2 weeks ago.
