H-Dog, I also sat the exam yesterday. Having previously failed it I feel your pain. This time round I really focused on learning the procedures precisely as CASA describe in their May version of the ATPL exam info booklet.
I'd have to agree that your quest for super accuracy is probably what let you down, as has already been stated here you have to simply follow the SOP and the result you come up with at the end of your workings should be spot on with one of the available answer choices.
