Matrices presents one the most difficult challenges to Praxis test-takers because of its unique vocabulary and brand of mathematical logic. For that reason, its also extremely fruitful for making large gains. Please click the image on the left to take a 5 question diagnostic assessment of your knowledge of matrices.
Irrational and imaginary (or complex) numbers also present an significant challenge to the unprepared Praxis test-taker. While irrational and imaginary numbers are significantly difficult mathematical concepts, they have had a terrible time of trying to go mainstream, and because of it most hopeful mathematicians don't know what they don't know about these number systems and their properties.
