Get someone to ask you the question bank! I assume you have highlighted the CORRECT answer of each questrion at the back of the manual!
If you can answer every question correctly, this including the simulated stalk questions where you need to identify 8 of the 12 things recommended for say a highland Red days stalking (only using those numbers as a "For Example"). Then you should be OK, however, if you are in any doubt to any answers, do the course. I think I would have passed the assessment only, but I read and read the manual over and over, including the question bank.
What I will say though is I learned alot of "out of syllibus" information, from the instructors and other students through conversation.
