### Who Should Take?

Students should have a mastery of basic algebra up through and including quadratic equations before taking this course. Typically this class follows our Introduction to Geometry class.

This course goes beyond what you would find in a typical honors Algebra curriculum. Algebra courses vary widely in their definitions, but our Intermediate Algebra class covers topics typically found in honors Algebra 2 and Precalculus classes, as well as many topics that are not found in most other curricula. Students who have completed a typical honors Algebra 2 course elsewhere may be ready for Intermediate Algebra.

### Required Textbook

 Intermediate Algebra By Richard Rusczyk and Mathew Crawford A comprehensive textbook covering Algebra 2 and topics in Precalculus. This book is the follow-up to the acclaimed Introduction to Algebra textbook. In addition to offering standard Algebra 2 and Precalculus curriculum, the text includes advanced topics such as those problem solving strategies required for success on the AMC and AIME competitions.

Intermediate Algebra has been an excellent course! The class has been extremely fun and challenging, and it is amazing how much material we have covered in this amount of time!  To have a great group of peers to communicate with in class and on the message board is awesome! As a homeschool student, I use Art of Problem Solving online classes as my math curriculum, and I am truly grateful to have such a great resource for my education. AoPS rocks!
