That's unfortunate but chin up you will pass it next time.im my day you simply did an aptitude test of various math questions,English and general knowledge, just things you learned at school. It was very very easy then your name was put out to potential employers .I passed say on the Monday and got a phone call the following week for an an interview and that was me.its getting harder now to get apprenticeships with mid size companies with 10 employees say due to the rise in sole traders .I really feel for someone wanting to get into the trade now.i was lucky I got a varied apprenticeship, domestic,commercial and industrial. Spent my first year mostly making off lengths of micc ,the good old days .I distrust large national companies im not sure they would have your development at heart and there knowing to get shot of you when there super stadium build is complete .where are you based
