I sat my PPL exam with ASL - went in with everything including recommended WAC's and calculator (non-programmable, bought especially for the purpose) only to discover that they provided copies of the WAC's and a calculator. Agree with aplund that VFRG/ERSA are a must - also make maximum use of the material you're allowed, look up anything you're not absolutely 100% sure of, you've got plenty of time.
I was expecting some interesting 1:60 nav stuff, and sure enough there was a question that looked like it would need some of that but (after wasting time plotting lines on the chart and doing some 1:60 calculations) it turned out to be much simpler than that! Good reason to read the question properly before jumping in!
Like aplund, I spent pretty much the whole allotted time - the last 30 minutes or so going back through my answers. And just as well, because I found one answer I couldn't reconcile to my calculations, I'd marked the wrong box. And nearly destroyed a perfect score!
Having said that, quite a few left after a couple of hours or so - just proving you have plenty of time so no need to rush.
