Study.com has engaging science courses in biology, chemistry, physics, environmental science, and more! Our self-paced video lessons can help you study for exams, earn college credit, or boost your science grade. Choose a course below and get started!

How It Works

  • Choose a science course: We offer physics, environmental science, Earth science, chemistry, health and biology courses to middle and high school students as well as college students and adult learners.
  • Watch fun video lessons: Illustrated video lessons make it easier to take on even the trickiest science topics, like stoichiometric calculations and special relativity.
  • Take practice quizzes and tests: Use these resources to assess your understanding of course material and pass your own exam with flying colors.
  • Get help from our science instructors: Our experienced teachers are available to answer any science questions you might come up with.

Who Are Our Courses For?

  • Middle school students who want to earn better grades in science
  • High school students taking AP courses or preparing for exit exams and college admissions tests
  • College students who want to earn general education course credits
  • Adult learners looking for GED study guides or continuing education courses
  • Prospective science teachers preparing for subject area licensing exams

Why Our Courses Work

  • Learn where you want: Our online course format allows you to access study materials on your mobile device wherever it's convenient for you.
  • Study at your own pace: Watch as many lessons at a time as you want and review course content as often as you need.
  • Track your progress: See how much of a course you've completed with a personal dashboard that displays the number of quizzes passed and lessons viewed.
  • Access all courses: Find resources for other subjects you'd like help with or explore additional science topics. You can access all of our courses with the same subscription.
