Go for it it will be the best thing you have ever done .
If you can try and go for a multi skilled engineering course , company's will fight to employee you if you can , as you can do all of the trades and they don't have to get three different blokes in for one simple job .
I done my multi skilled engineering apprenticeship when I left school as I was lucky enough to pass a test at a place called seta http://www.seta.co.uk/
they trained me up and sent me to collage , i was lucky enough to be tought many different trades and different aspects of those trades i.e installation and maintenance In Electrical , Mechanical, refrigeration, welding, milling and turning , joinery , building .
Good luck
