Was that using a CRPx? They really are a piece of CRaP judging by the answer spread I've seen from them. I recommend the CR type eg from Jepp. Not popular in the UK though - I think because instructors there aren't familiar with them, using what their instructors used who, in turn, used what their instructors used etc. My CR5 is the smallest, and therefore least accurate, of the type and was quite accurate enough for Oz, USA & UK ATPLs and Oz IR.
On the topic of exams, I happened to do the FAA Advanced Ground Instructor exam today (91%. Yay!) since the AGI is a certificate I can get for bugger all effort. There were several questions that had hints to the correct answer elsewhere in the exam or its workbook, or I didn't need to calculate the whole thing because only a single option had that correct result amongst the other items that were supposed to be calculated.
Later...
Forgot to mention: Most of us know that the FAA's exams are all multi-choice and typically only have three options, but I discovered during today's exam that they also include E6B and calculator applets in the exam software! Don't remember that from years ago. Still found it quicker to do some problems on my Jepp. CR5 whiz wheel but it was nice to have an alternate method to check my calculations. Rather different to UK & Australian exams!
