He holds a bachelors degree in psychobiology from the University of California, Los Angeles, and a master's degree in education from Pepperdine University. He gravitated toward teaching physics due to the challenging material and a sustained belief that physics does not need to be mysterious and difficult, but rather comprehensible and accessible. Greg Young has been teaching high school science for more than twenty years. He currently teaches Honors Physics and Chemistry at San Clemente High School in San Clemente, California. He holds a bachelor's degree in biochemistry from the University of California, San Diego, and a master's degree in science education from USC. Having always been interested in science and how to make it relevant to others, Greg's interest in teaching is being able to create interactive lessons that engage students in their learning and form a relevant context for difficult concepts in physics and chemistry.

About the Publisher In the 1930s, Manuel H. Barron opened a bookstore in Brooklyn, New York. People from the community asked Mr. Barron about books that might be available to help their children study for the New York State Regents exams. After realizing there wasn't anything available, Mr. Barron created his own study guides. 80 years later, Barron's has helped millions of people prepare for their next step.
