In reply to michael1994:
Michael I'm a D&T (PD) teacher. I assume you are doing this survey for AS/A Level?
My advice:
Take note of the comments above from your 'cutomers'. Revisit the survey. Correct any spelling/grammar mistakes. It requires quite a bit of keyboard input and the questions are open. Could you simplify and ask closed questions with multi choice answers? Is it possible to be more focussed on what you need to find out and simplify the Q?
Having said that when my students use forums to gather user info I often get them to invite people to say what they want about a product. You don't get as many replies but often the ones you get are more useful and considered.
At any rate good luck with your work.
