DO NOT get these, as they are out of date and not in line with AMD NO.1 of BS 7671. I have had students turning up with these and quoting from them and when i have looked in them they are FULL of incorrect information!!!! Fully up to date, no they are not waste of money. P.S I work in a FE college as a senoir electrical engineering lecture. One star given as unable to give none.
