Hi there.
Hi here is a handy thread

I lay my work out as follows...(example below)
UNIT 23
2.3: Then the question here.
Answer here underneath the question.
The internet is also a very useful source to research information for any questions you are stuck on that way it will give you a rough idea of what to put, alternatively you can use the search button that is on the level 3 diploma and NVQ page to the top right, the drop down gives you a box, just type in your question or if you want any information on a specific thing for example EYFS or safeguarding.
Also it does help if you post the actual question rather than just 4.1 etc.. because some people have different kind of courses :)
I wish you the best of luck with your course. If you ever get stuck on any of the units and criteria, please don't hesitate to open a thread and ask, there are a lot of helpful ladies on this website.
