Math Olympiad Contest Problems for Elementary and Middle Schools

I borrowed this library book for my DS9. I think our school does Math Olympiad competition in later grades. I did not see any reference to age or grades with the different problems. My son scored 145 on Math broad score on Woodcock Johnson. He is in 3rd grade doing 3 & 4th grade math this year and it seems too easy. He is having some check your work issues/follow all directions issues. He almost never gets anything wrong in school this year unless he has a not being careful issue. He is straight As so far. Is this a good book for a child to use on their own? Any suggestions for using this?
