I did the exam today and got in the mid 90's. As suggested be very carefull with your trim sheets adding up your zone weights and converting the pax into units. I had 2 zones where they were 17.5 and 18.5 trim movements.
Also be carefull in your zone load movements that you get the scale right. I went back and re checked my trim sheet only to have to make an adjustment due to my nerves i think!!
I also got 1x landing weight question. I found the 727 manual graphs to be better quality than the casa provided.
The rest of the exam was a heap of Net and Gross gradient, ballasting x 1, balanced field, V1, V2 and LRC. and a couple of compartment questions.
NOW Back to those beers 1 to go!!
