OP - the girl in the example above came to me in year 4 for maths help, which we did and which did help her in class. At the beginning of year 5 mum asked about 11+. I had a very frank conversation with her.
I our area the test is 25% English 25% VR (not the silly codes and stuff) 25% NVR and 25% maths.
as far as we know (although this is not published anywhere) you don't have to pass each section, you have to pass overall (this is not true in every area, in Kent you must pass each section)
I told mum - she will pass English. With practise, she will pass VR. She may even pass both of those very well. I don't know about NVR, she will probably fail maths.
What I can't say is whether overall she will have enough to pass, given that maths is only 25%.
The thing is though, the maths curriculum for the CEM test is the same as the curriculum for school, so any improvement in her maths would also help her in school.
She opted to go for tutoring and see how we went. She worked hard on English (mostly comprehension etc) and VR. She did most of that at home. She used vocab cards to increase her vocab, and tightened up her spelling. She was quick to learn the SPAG rules that she was hazy on and so by the end her marks for English and VR were high.
She was OK at NVR, not amazing but enough to pass. We worked on those areas she struggled with (nets of cubes etc) and I taught her one or two methods that helped. She will pass NVR.
Maths - we worked at this all year. I made sure she was very strong on all the areas she understood and we practised putting that into questions. She eventually got to the point where she could do most 2 step questions (like in my example, 2 calculations to make) as long as the basic maths was straight forward. We abandoned some topics, she never understood ratio, and time. She was good at learning methods, so amazingly got percentages, once she had a method to learn, and the questions aren't complicated.
She never really got the questions which required more advanced concepts. On a good day she would score 40-50% on her maths.
We re-evaluated at each point with mum. We talked about all options. I was very blunt with her, will she cope with the maths at GS? BUT I did think that she would flourish at GS in every other respect, she loves science, naturally fascinated by History, fantastic at English, a natural thirsty for knowledge kid. I encouraged mum to find good options, and there are several good options around.
So last week she took the exam. I have no idea if she passed. In the practise papers we did her total was bordeline.
The only thing I can say is that everything she has learnt feeds into her school work. She proudly told me she had been moved up a maths set, and when her teacher was explaining fractions she felt really confident, because we had worked on that.
She was a kid who loved her sessions with me, and loved doing the homework. She just loved learning/school. I would not have been able to do any of it if she wasn't like that.
