I took the national exams twice, the first one I got 19.9 in mathematics and the second one 20.

The book is very detailed to the point that it can tire some children. It is twice as long as the corresponding EPAL math textbooks, but I think it's worth it for the extra exercises and examples.

I recommend it for a child who struggles with math and wants to see many examples and detailed methodologies.

If you are better at math, I suggest Savvas' book. I have finished both textbooks. Savvas' book has better/more difficult exercises.
