Guys I think that my experience will be really useful for a lot of you , I did the bq on 28 August , WITHOUT PREPARING ANYTHING , I just reviewed some math ( the hardest part imho is logical reasoning , quite hard ) , without any skytest or similar , and I passed quite easily , many guys that used skytest failed , we were 15 and only 5/6 passed.
the bq is not so crazy like the dlr ...
