In this course, you will master all concepts of College-Level Algebra and Trigonometry, from beginner to advanced, with our step-by-step video tutorials and test your knowledge with over 3500 Practice Test Questions. The concepts you will learn are fundamental to success in higher math classes such as Calculus and Linear Algebra.

******************PLEASE READ BELOW BEFORE PURCHASING THE COURSE******************

The Pre-Calculus course that I offer on Udemy is a more concise version of this course. This course is meant to cover all of the major topics of Algebra, whereas the Pre-Calculus course only covers the more advanced topics. It starts from section 10 (graphs and functions) of this course.

If you are struggling with basic Algebra (factoring, polynomials, solving equations...), then this is the course for you, otherwise, the Pre-Calculus course may be the better option. This course contains more practice questions and quiz questions.

Both courses contain the same Trigonometry content.

Please do not buy both courses under any circumstance! If you buy this course, you will have access to all of the materials from the Pre-Calculus course.
