first of all, don't ever feel stupid, your teacher is there to teach you, it is her job to explain it to you in a way that you understand.

secondly, i have been doing this for 2 years now, i did one unit, then another, passed it to my assessor who had it for 14 months! assessor was also my teacher at school, and my friend, my fault, i should have spoken to my IV and got it passed on to someone else, my folder lived on my dining room floor for a while, then got moved to the bedroom, then in a cupboard. we then got a new teacher who was very pro nvq, i have completed 4 more units in 6 months! but there were very very tough days where i just wondered why i had started. it will get better i promise!
