I'm about to join the ranks of those who type out logic game questions for help..

Sorry if this one's been asked already, but here goes..
Dec 1996, Game #3
An attorney is scheduling interviews with witnesses for a given week, Monday through Saturday. Two full consecutive days of the week must be reserved for interviewing hostile witnesses. In addition, nonhostile witnesses Q, R. U, X, Y, and Z will each be intervied exactly once for a full morning or afternoon. The only witnesses who will be interviewed simultaneously with each other are Q and R. The following conditions apply:
X must be interviewed on Thursday morning
Q must be intervied at some time before X
U must be interviewed at some time before R
Z must be intervied at some time after X and at some time after Y.
Here's what I got:
QR>X>Z
QR>U
Y>Z
AM __ __ __ __ __ __
PM __ __ __ X __ __
M T W T F S
And QR can't go on Saturday or Friday afternoon, since both U, X, and Z have to go after.
I'm finding all the questions really hard, and the QR thing and the block for hostile witnesses is screwing me up as well. A little guidence would be a great help, even if it's just helping make the bigger inferences to point me in the right direction...
Thanks in advance everyone!
