Slightly off topic, but I recently sat the CPL AIR LAW and found that I used NONE of the permitted charts or maps. I was quite disappointed as I'd gone out of my way to purchase the Hobart VTC and TAC, which I'll never use in operations before they expire.
All the same, an extra $20-40 spent to ensure you're fully kitted out to pass the exam is a small insurance. Imagine having to fork out another $200 odd for the entire exam again if you failed because of this.
