Core Videos - Praxis Science Content Knowledge (Sample - Phenotypes, Genotypes and Incomplete Dominance)

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

Click below to play a sample Core Video from our Praxis Science: Content Knowledge (5435) Online Prep program.  This particular video focuses on understanding phenotypes, genotypes and incomplete dominance, a concept that appears frequently on the Praxis Science test.  

When you purchase any of our Praxis Science Content Knowledge Online Prep programs, you'll get Core Videos like this one covering every key Scientific Methodology, Techniques, and Development, Physical Sciences, Life Sciences, Earth Sciences, and Science, Technology, and Society 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!
