Core Videos - Praxis II Mathematics Content Knowledge (Sample - Determinants)

Your Own Personal Teacher... From the Comfort of Home

Click below to play a sample Core Video from our Praxis II Mathematics Content Knowledge (0061) Online Prep program.  This particular video focuses on finding the determinant of a matrix, a concept that appears frequently on the Praxis II Mathematics test.  Here we discuss several techniques for finding determinants, as well as the underlying logic you can use to help deduce the needed formulas in case you forget them.

When you purchase any of our Praxis II Mathematics Content Knowledge Online Prep programs, you'll get Core Videos like this one covering every key Algebra and Number Theory, Measurement, Geometry, Trigonometry, Functions, Calculus, Data Analysis and Statistics, Probability, Matrix Algebra, and Discrete Mathematics concept you need to pass.  You'll learn the same key subject matter you would in our live classes, as well as strategies for success on the various multiple choice question types you can expect on the exam.  Then, once you are confident with the underlying subject matter, you can watch our Smart-STEM Virtual Tutoring videos, in which a tutor will show you how to apply your knowledge to the specific question types you are most likely to encounter on the actual test.

Both our Core Videos and Smart-STEM Virtual Tutoring videos are included in all our Online Prep programs!
