My wife is a post 1997 licence holder and has done her D1 test last year, she also do the initial cpc for this category, if she now does cat D does she need to do another cpc or does the D1 cover this ?
if she has passed the initial for D1 then there is no need to do it for any upgrade to D
Thanks 
No theory either for D - just the practical test including the reverse
So am I correct in thinking that theory for D1 covers D but if you had acquired rights D1 you would have to do theory for D

Yes that is correct
