I took it last week at atp and got a 94% on it. They eliminate all the redundant questions and it ends up being a bank of about 580+- questions rather than the 1800 in the red book.
you start at 8am and got until 6pm, but if you feel your ready you can take the test, i finished up about 3pm.
i reccomend it if your short on time or just wanna get it done..
