Aerofoil1,
I am slightly alarmed by your post
I've been told to plan from uttoxeter to wrexham and then down to Hereford a fair old run!!
It is now Wednesday and your test is scheduled for Sunday. Examiners are advised not to give the candidate the route more than 2 hours before the flight. This is to see if you can plan the flight in a realistic time scale and to prevent people asking around for advice and possibly even going out and flying the route. The Examiner will brief you prior to the test on exactly what he wants you to do, so don't go asking other people. You should have read
CAA Standards Doc 19 before you meet the Examiner. Have you done so? The route you plan should be triangular, finishing up back at the start point so that you can produce a fuel plan, it is not open ended as you imply. You appear to be starting from either Tatenhill or Derby.
I wish you all the best and hope the examiner doesn't do anything else non standard.
