Do you find this easy or hard?

Very easy.

Yes - I'm a Grammar Guru, apparently!

Easy, Peasy, Lemon Squeezy - 100% - which I would expect that everyone over 60 would get.

Simples!

If I hadn't got 100% there would have been something wrong with the questions!

I don't understand why the ones I got wrong were wrong .

I got the who/whom wrong.

91%

A cinch.

However !!!

Although I got the who/whom one correct, if i were asking the same question, I'd use who no whom. Because one does.

who not whom even

Very simple!

Scored 100%, Grammar Guru. I would also use who for whom in many cases.

....and I am happy to split infinitives!

I am a grammar guru also !!
Still it wiles away a Sunday afternoon !!

Apparently I had 97% - but only if I was wrong to choose "Why don't you go and lie down?" as a correct answer.. Does anyone agree with me, or am I the only one out of step?

That is correct. Can't imagine you (or your) getting grammar wrong, Elegran.

So what did everyone else answer for that one? If you got 100% you must have put "lay down" unless there were other alternatives that I missed.

100% - but admit to having to think about who/whom!

I'm a Grammar Guru too

I ticked '...go and lie down' and 'I lay down the book'. What else could the choices be?

It said those answers were correct, by the way!

97%

100 %
I'd say it was a simple test ...

Easy peasy. I am a guru too!
