Blimey, just completed the actual tests...
That SJT was horrible, so many of the answers were basically the same just worded slightly differently!!
As for the VSE, I didn't do great sadly.
Part 1 was nice
Part 2 I stupidly got 4-5 wrong
Part 3 I actually did better than part 2, think I got 2-3 wrong
So not holding out a lot of hope there!
The real one is not the same as the practice ones they tell you to print out, those were just to give you a rough idea of the type of thing the tests do. You get to practise first when you do the real thing, and you can repeat the practice if you like, so my advice would be to just get on and do it. Make sure it's quiet and there are no distractions!
