Khan Academy has thousands of articles, practice problems, and videos to help you learn a wide range of subjects. Click on the Courses tab at the top left of our site or search for a topic to get started.
Once you have chosen your course, you can look for the exact unit you want to learn or review. Select the main unit or an individual lesson to see relevant videos, articles, and practice exercises.
Once you choose a unit, you can take a quick unit test to see which concepts you’ve mastered and which you may need to practice more. Or, you can dive in from the beginning by doing the first practice exercises.
As you build confidence with concepts, put yourself to the test! There are exercises, quizzes, and unit tests in each unit, and a course challenge that includes skills from the entire course to help you demonstrate your understanding and track your progress.
Mastery Challenges are a way for you to review and practice skills you’ve previously learned in a course. It's also another way for you to level up or down in Mastery, in addition to taking unit tests and course challenges.
Set a schedule for yourself, and study at least a few times a week. That way, you’re more likely to remember the new things that you’re learning.
And finally, be patient and persistent. We know that sometimes in your learning journey, things will be stressful and frustrating. You won’t always understand something right away, and that’s okay! Your brain is like a muscle: the more you use it, the more it grows. We believe that you can learn anything.
You can view an Assignment report for any student by clicking on Scores under Assignments in the left sidebar.
You can track your students' mastery progress at the course level to see how the class is trending as a whole in the Course Mastery Progress Report.

In 1907, the United States became the first country to pass a compulsory sterilization law. The genocidal policies of Nazi Germany ultimately discredited the “science” of eugenics, but not before over 60,000 American men and women were forcibly sterilized to prevent them from having children.
The purpose of eugenics was to eliminate "undesirable" attributes from the human race. Since poverty, mental illness, and different racial and ethnic backgrounds were considered biologically undesirable traits, the process of sterilization was used as an unethical means to "cleanse" humanity of biological weaknesses.
Most colleges consider your high school transcript to be the single most important factor in your college application. Though taking (or not taking) any specific class will not determine the outcome of your college applications, there are certain general guidelines for selecting classes during high school to put you on the most straightforward path towards admission at a more selective college.
More selective colleges prefer high school students who take at least five core academic classes most semesters (math, English, history, science, foreign language), in addition to a few classes in the arts. Let’s take a look at these subjects in more detail to prioritize potential courses:
