My name is Sithy H. Maharoof, author of the Praxis® Exam Prep: Physics Content Knowledge. I was awarded the ETS® Recognition of Excellence in 2011, after successfully completing the Physics Content Knowledge Exam. When I prepared for this exam in 2011, I had been out of school for about ten years and it took a while to figure out a method to prepare for the exam. To my dismay, I found very little practice materials for this test. Thankfully, I completed the exam with a near perfect score! After passing the exam, I embarked on a project to create practice exams so that prospective physics teachers will have chance to put their knowledge to test.
