You fill them in for four weeks to get used to the plans and you hand them in for the consultant to see if you need any help.
After that, you will be given one if you are struggling and need help - they are a tool for the consultant to help you.
Im not sure what you need to remember though as really, all you need to think about is your A and B and count to 15 for your syns.
Write things down if you want to, but you shouldn't get them given by a consultant after the first four weeks unless you need help.
