I can only support what's already been said. The whole set up is first rate and a credit to the team at BGS.
I have just passed all 14, also with a 93% average, at the first attempt. It's taken about a year while working full time.
The guys and girls are very helpful and supportive. They have the patience to give you a detailed answer, even though they have probably answered that same question a hundred times before.
On the brush up they add in humour to make even the hardest of days seem like fun. The atmosphere at BGS HQ is great and I thoroughly enjoyed my four weeks there.
Oh yes, and Alex's ADF impression has to be seen to be believed.
