Who Should Take?
Students are ready for this course if they have mastered arithmetic with fractions, decimals, percents, negative numbers, and integer exponents. Most students who have completed a typical Prealgebra course are ready for this course. Students finishing our Beast Academy curriculum should take Prealgebra 1 and Prealgebra 2 prior to taking this course.
Please note: Our Algebra sequence will likely not match up exactly with your school's. Most students who have completed a Prealgebra course are ready for this course. This course covers much of the algebra of a typical honors Algebra 1 course, some of the content of an honors Algebra 2 course, and some additional material not taught in most standard curricula. Visit our Recommendations page for help in choosing the right class.
