I think the OP said her daughter was in YR5 as sitting the test in 2017?
You have started at exactly the right time! Keep ploughing on with lots of variety - we did Letts, CGP books, GL Assessment packs plus BOFA online in the months leading up to the test, all in addition to tutoring.
If I or the tutor spotted something DS was weaker at, they or I would go back to basics and cover the topic with him in-depth, plus find lots of practice questions for him to work through. This kind of gap analysis is really useful, particularly with maths.test info removed by moderator. Please refrain from discussing test content, number of questions etc as there maybe late sitters.
we didn't in much detail and it came up in the Kent Test 2016 for the first time!
