So I've recently finished my level 3 and I've been having a good look online at the online course and the 3 day course from mainly two providers (tradeskills4u & niceic) but its bloody ÂŁ400+!!!! I've been on YouTube watching alot of sparkyninjas walkthrough of the book and wondering why not just do that and pay for the exam! Is it a good idea or do i need the classroom?!
