Final stage at BA is another numerical reasoning exam, verbal reasoning, an interview, aptitude tests, and a medical if i'm not mistaken.
So I wrote this earlier believing it to be the case, but somehow cannot find out where on earth I read about it!
Part of me is thinking I might have been told it during the interview at CTC (I asked what happens if I go through) however without any written evidence I am doubting myself somewhat... due to nerves that entire day was something of a blur.
It may be my confusing BA's standard application process with the FPP also. The medical part could indeed be for another day.
