I would be carefull with this crowd. My frined had a very distressing experience with them. He was being shouted and screaed at by one of the instructors in the Sim sessions. He failed his LST which is not unheard of and they told him he was off the course. He was really left high and dry as he had paid all the money out and now had no type rating to show for it or the line training.
I would have to point out that he was not struggling or lagging behind in an unusual way or was he a particualr weak student, this guy just took a dislike to him. Just be carefull and know the risks of what your getting into!
