Good luck!
Remember, the inspector wont expect you to have completed the SEF, so do what you can, well, and don't worry about filling it all in!
It is a working document so they don't mind if its not complete, as long as they can see that you have made a start on it, to show you are evaluating yourself and your setting they should be happy!
Thats what our inspector told us, and we didn't complete ours, but were graded 'outstanding'!
