Different country, different exams, different laws, but here's my advice.
Disregard the folk who misinterpret, mistype and misadvise you on air law and go straight to the source. Study for air law by reading the actual aeronautical regulations and standards. They change faster than the study books, and any typos in them are law.
Two years down the road when your boss says you're good to go and you know you're not, you should know how to pick up the actual book of regs and show who is right. It's your licence.
