Interesting posts on here about shodan tests. I took my shodan in August and the whole test took approximatley 2 hours...but bare in mind there were 11 people up there with me.....so i gues my actual 'performance' took no longer than 15 minutes in total. I think this is because a shodan test is really only the icing on the cake....what makes a shodan is not what he or she can pull off in a grading, under examination conditions, but all of the work he or she has put in in order get to that point of grading.
To be made a shodan purely on what you can pull off in a grading, in my opinion, is not the most sensible way of doing it. You can allude it to driving tests......who will be the best driver?....a person who has had 50 driving lessons and then passes the test or a person who has taken a crash course and then passes the test?
I guess it all comes down to experience....as so many things do
