Hi passed city and guilds 2360 level 3 back in 2004. 2 yr course. When left college i did the 2391 course, but failed it due to lack of knowledge experience. College put us on it to earn money. 2 passed out of 12, some very experienced. Any way just been told im not a qualified electrician. Ok im very rusty with calculations etc. So what course do i do next to better myself. Thanks
