I did G4 and I enjoyed it. I got home and realised I hadn't done any interval questions and had a brief bit of confusion - so I hiked out the past papers I'd done and saw sometimes you get intervals, sometimes beaming, and so on. So that was all OK then - I hadn't noticed that they changed what goes on in different papers!
I ended up doing to rhythm-to-words option and used compound time

That's the bit I'm sure will lose marks if anything. The 'factual' stuff should be OK, I did check everything but you can think something is right, check it and still think it is right, but actually be wrong.
I left after about an hour, about half the people had left by then. Interestingly, in previous years they had split us in to room by grade (e.g. G1-3 in one room, 4-5 in another, etc), but this time we had four rooms and we were all mixed up. My room contained G2-5 people. But they used enough rooms that we could have a two-seater desk/table each, rather than before when we have had to share. So I think that worked well.
The room I was in - and had to wait outside for a while - that was right by the invigilator's table where they were checking everyone in on arrival. And I was first to arrive

So I know that nobody at my centre last night was doing G6 or above.
When I got home I just wanted to get out the G5 stuff (I now know I will be around in June so I can do it then if I want)
