Don't worry, i'm also 18 and have passed stage 1 and 2 and waiting to go for stage 3 (d-day 20th November!). As tim said life experience doesn't really have anything to do with it in stage 1 and 2, it's all about how good your brain is! age doesn't really matter. Obviously i can't speak for stage 3 because i haven't sat it yet, but i'm not too worried about my age, i'm sure i'll find examples to talk about for each of the competencies and will let you(and the rest of the forum) know how i get on. good luck to you!
