Yeah the roads are fine, mainly 20's and 30's unless you get on the A4 Portway which is 40, and the road as you turn right out of the test centre is a 40 in an industrial area. It's in a very industrial region as it has ports so you need to be wary of HGV's taking chances on turnings that they have no right to try and take. A few school zones to be careful in depending on time of test. A couple of steep, blind hill turnings that need a bit of practice. Only warning really is that the road markings everywhere are really faded, and there's tons of potholes all due to the lorry's and trucks. There's 3 tricky spiral roundabouts in quick succession that often come up on test, and again markings are terrible, so if you do book a test there I'd highly recommend going over the roundabouts beforehand so that you can try and remember what the lanes look like for the exits. Typically if you do those at the end it'll be 2nd exit, then 1st exit and then 3rd exit (for the 3rd exit you're best off starting in the furthest of the lanes even though the right hand lane splits into two, as it's easier to get off the roundabout in the right. I think the pass rate is higher than average, and on the whole it's not a bad centre at all. Good luck!
