hi mrs s, don't worry too much about it!, i started my nvq in nov, just finished my 3rd unit, once you get going it does not seem so scary!
my assesser is quite good and as a childminder visits me regularly, i'm not doing the child-minding one but the ccld 0-16's nvq. all i can say is just to try and enjoy it and it will all slot into place, let me know how things go!
