It's best to make your own decision about what to do - if only because this is a public forum, and another poster who sees it might be going for the same post! A Head on a TES Forum said recently that 4, four, out of 6 candidates did a lesson that had been discussed on Primary here. She recognised it, but even if she hadn't, the fact that 4, four, of them did the same thing would have been a bit of a giveaway! So choose and plan your lesson (including Plan B in case you get the level wrong), and pop over to the JobSeekers Forum and open the two Interview clickables inside the Welcome thread to get advice in general on preparation for an interview. Best of luck. ___________________________________________________________ TheoGriff. Member of the TES Careers Advice Service.
