My daughter was having problems with her Maths and kept failing the several mock examinations. We were not given any examples from her school.. I phone and was told the name and what to buy. So, I did. What I discovered is that this book covers all they need they need to know for they 11 year examinations. My daughter had not even been told, shown, or even taught this level of maths.
The book is very easy and yes at first you will have to sit down with your child until it comes back to you as it set out different way then parents are taught. Never the less its still easy and will do the trick just make sure they do the questions.
Now my daughter gets high marks in the mocks as its a set of generic books and covers every kind of maths problem and solution. Just as a not we all so bought level 1 and 2 and they were just has helpful.
What they were doing in there classroom was concentrating on just one area so that they would at least get a grade an grade so the school would not loose any funding.
Just do yourselves a favour,
