Well that's reassuring, that someone felt the maths was hard. From a balance perspective.
My son is extremely able at maths, so obviously that's a factor, he found the junior maths challenge quite hard (he got a silver), so that's his level.
I don't think the English should be limiting, you can tell a lot from the quality of any kind of prose, certainly there's much with my son's that I'm able to point at as less than ideal.
Obviously not terribly creative as an exercise, but I think in terms of the senior school curriculum, these English tests are more about testing your ability to write essays and cope with the humanities than actually a real interest in the creative spark in a given story.
Not sure about the vr, we were working intensively on vr before sitting for tiffin (late November) but none done since then, except for one yesterday, which he got about 96% on, so it didn't seem like he'd lost anything there, but it could be that he couldn't do one or two (he said he had to guess at one about inserting a three letter word into other words?), and judged on that fairly limited basis.
