They might give you a place to start. Often what beginners want is to know what questions to ask. These pages might raise more questions for you than answers, but that's not a bad thing.
Books:
Electrical Installation Work - Brian Scaddan - Newnes
Basic/Advanced Electrical Installation Work - Trevor Linsley - Newnes
Waterstones branches stock both of these; they contain all the theory you'll need for the C & G courses, but ask your college if they have a recommended course textbook.
Best of luck
