Fifty Lectures for Mathcounts Competitions (3)

They are very good books.

Very good!

If you feel that learning math is too easy at your school--most often school teach kids too slow. These are the books can help you learn more advanced skills. Even for me I feel refreshed by the books in terms of problem solving skills. This sent of books covered all topics you need to learn from 4th grade to 8th graders. Good books for preparing mathcounts test as well. Thanks for the authors for their math knowledge and problem solving experience,
