### Who Should Take?

This course is appropriate for students in grades 6-9 who have mastered basic algebra up through solving linear equations and manipulating multi-variable expressions. Students who have completed our Introduction to Algebra A course should have sufficient background. This course is roughly the same difficulty as our Introduction to Number Theory class. For those preparing for contests, this course should help with MATHCOUNTS and the AMC 8/10/12 tests.

I had so much fun in this class! It was BY FAR my favorite class this semester! I think it was very informative and really interesting and I would highly (very, very, very highly) recommend this class to anybody with no hesitation! Sign In
