I did the GAPAN tests around 18 months ago and found then very usefull indead. As they are not run for profit the advice and debrief you get afterwards becomes invaluable. Even if it gives you a confidence boost before you start then the 150 pounds can be easily forgotten. Or in the nightmare senario of discovering that you just do not have the skills then you have just saved 50,000 pounds and alot of hard work. If you do not give it a go then you will probably be asking yourself should you have or not. It gave me the confidence to carry on and it also made other people there with me think again. My advice is that either way its a postive step.
