Thanks to those who have given positive feedback, it's very useful to draw from the experience of many others. Will be discussing with my instructor as well, but do feel a bit more prepared now.
I think part of the confusion was down to the fact I've never flown from an airfield with ATC. Stapleford has a radio operator and I've become quite familiar with their circuit joins and exits. Looking forward to a new challenge!
Thanks again for the input, will provide an update on how it goes. Fingers crossed for the weather.
