I practiced all possible permutations of the test route on an old version of MS flt sim....lotsa times, in addition to all the usual synth trainer stuff. It's cheap (free!) and i found it really helped on the BIG day! No big surprises, (pretty much knew all the tracks/LSALTS by rote!) which left more spare mental capacity for the usual engine failures at random points. First time pass on all aides, so couldn't have done any harm!
Good luck.
