Hi, I haven't been on the site for quite a long time, but i am doing NVQ 4 CCLd, Have been sitting all day trying to sift through some of the knowledge questions. I came across the site by accident again and when I started to look through the threads, I found some of the help I needed. Thanks to everyone for sharing ideas. Now I can go and try to work on K4D806 and K4D807.
