Farnborough has some nasty test routes, don't get caught out at the box crossings, and don't forget to speed the hell up when you go onto the a-roads. Get on first name terms with your mirrors too.
8:10 is a horrible time, it'll either work in your favour or make your test harder. Rush hours can burn a lot of time and make it so as long as your clutch control is good; you'll jump straight into independent driving, then a manoeuvre and it'll be over. On the downside, everyone at this time will drive like an idiot and so your own awareness and planning needs to be that much more on point. 11am is much better.
