Were the "essay questions" those two (fairly brief) questions about 150- 300 words long?
I think, although i'm guessing here, that mentioning BA in my application might not have been a wise move. Afterall if you tried and failed at the last hurdle with them then it might brand you as someone who doesn't have what it takes. I may keep quiet about it in future
Oh well, I wasn't 100% committed to this application as I was with the last one anyway. It makes sense that I didn't make it in.
