Rudeboy 500: I understand where your coming from, as will a lot of the other guys. But if we work out the Answer for you then how will you get any further forward ? If you ask for help then we'll give it, but we won't do your Course work for you.
Once you've finished & hopefully passed your course, what happens if you come across the same situation out on site ?.
As for the boys takeing the P well yes it happens, but you get out on site working along side a load of Hairy a**** builders or go to do maintenance in a Factory full of women working on a line then you'll get a whole lot more of it. It goes with the Territory.

Hi peterdainels,
I understand what your saying, ever since I started the electro technology course from level 2, the lecturers have some what been under par in their way of teaching.

Some Lectures cannot understand that all students coming in to this industry are not working in the electrical industry or have anything to do with the electrical industry.

Take my example I don't work in this industry I do 3 hours a week at college 6pm to 9pm trying to absorb as much as I can by the time next week comes, only 10% of what I learn't is still in my head, this is because I have work commitments, family commitments.

The lectures should ask what industry you are in ? and go from there I am in my forties plus, life at the minute is hard trying to keep a job this is why I want something to fall back on just in case the inevitable happens and I lose my job due to redundancies.

This college course in like a fast track course and City and Guilds don't make it any easier what we are being taught and what comes up on the exam paper is nearly always completely different which totally annoys me. There question are based around an everyday working life of an apprentices.
All they want to do is make money

sorry for being so bitter.

Thanks

This is why I posted my template in post #2 to try and help give you a bit of understanding rather than just answer it all for you.

Rudeboy don't take this the wrong way but irrespective of level of students etc.. Any course you'll undertake will only give you a basic understanding of whats being taught and it's expected of students to undertake further research/reading to build on the knowledge

To just go to college for 3hrs a week then do nothing else in-between is asking for trouble and yes I know you have other commitments but, you have to find the time to read up further, maybe you should speak with your wife about it to let you have a break from kids etc

I also did my 2330 lvl 2/3 at a fast track provider so know the commitment thats needed to learn something new without much help from lecturers and it can be tough but if you want the pieces of paper you'll receive at the end of it to be worth anything you have to put in the time and effort esp in todays market place were colleges are churning out DI's at 10 to the dozen, you have to be able to stand out

If you're struggling with theory etc, i've got the basic and advanced Tinsley books that you can have cheap?

hi rudeboy,
i can understand what your saying and i would never knock anyone for trying to better them self, but your own post say most of whats wrong about the these courses 3 hrs a week with no on site practice its gonna be hard, idont think many people could learn a trade this way.the main part of learning is the site work/experiance which u are unable to obtain due to your comittments. the college mybe rubbish but i m saying and others have said before college is only part of the training ive only just join this site this month but what im seeing is alot of questions been asked about stuff that any good experianced spark should know.u can learn theory till it comes out of your ears but theory don't pay the bills. this site should make it compulsary to list what u are to join ie electrician, apprentice,adult improver, householder then members would know how to reply.

also everyone seems to think he wants the answer and get it the easy way but in my opinion its better to be shown how to do it before trying to do it wrong its easier to understand something if you knwo how its done if that makes any sense lol

Hi peter: Maybe we all think he wants the answers given to him from the title, Lenny posted a link in post 2 which should have explained things & in post 12 Fuzzy laid it out quite simply.
