4)search
5)u may get error messages, no appointment available or available dates. should you get the first two please continue to try. if last message be quick to select location and fill in your details.
its can be difficult (as i've not been able to reschedule my sheffield peo booking due to unforeseen circumstances to 08/10/12-12/10/12 from my original booking of 18/10/12), sometimes frustrating but keep on trying.
wishing you the best. pm if you have any direct questions and i'll be glad to advise as much as i know.
