AP teachers and AP students, you have a new, free resource: Khan Academy is now the official practice partner for AP.

We’re delighted to announce that we’ve partnered with the AP Program to offer free instructional videos, articles, and practice exercises designed to build the knowledge and skills needed for AP-level courses.

Lessons for the following AP courses are now available for daily classroom activities, homework, and independent learning:

AP Calculus AB

AP Art History

AP Physics 1

AP Physics 2

AP Chemistry

The Khan Academy team creating AP materials includes current and former AP teachers. External reviews by members of the AP community ensure all AP materials on Khan Academy align with the AP Program’s rigorous academic standards.

Our team is also working to add practice exercises to every AP course and will be making them available as soon as they’re ready.  (Our AP Calculus courses already have exercises.)

AP teachers, your insights and observations from using Khan Academy are the most valuable feedback we receive. Our goal is to make our lessons helpful for both teachers and students, and we can’t do it without you. Please send us your thoughts, no matter how big or small.

Here’s a video of an AP teacher who uses Khan Academy in the classroom. Bill Scott is the chair of the math department at Phillips Academy in Andover, MA.


Studying for the SAT for 20 hours on Khan Academy associated with 115-point average score increase

We’re excited to announce today that studying for the SAT for 20 hours on Khan Academy’s free Official SAT Practice is associated with an average score gain of 115 points. That’s nearly double the average score gain compared to students who don’t use our free test prep.

Official SAT Practice is free for everyone and personalized for each student. Start getting ready for the SAT today! We think a 115-point score gain can make a real difference when applying to college.

If you don’t have 20 hours to practice, don’t worry. Shorter periods of time also correlate with meaningful score gains. Six hours of study on Official SAT Practice is associated with an average 90-point increase—no small bump.

We’re also excited that more than 16,000 students from the class of 2017 who used Official SAT Practice improved their scores by more than 200 points. Way to go!

Together with the College Board—the maker of the SAT—we studied data from nearly a quarter million high school students from the graduating class of 2017 who took the PSAT/NMSQT and the new SAT in the past year. Score gains were consistent across genders, family income levels, races, ethnicities, high school GPAs, and parental education levels.

Since its launch in 2015, Khan Academy’s free Official SAT Practice has been used by more than 3.7 million students. We’re glad so many people are finding it helpful!

* Nearly 40% of all test takers report using our free Official SAT Practice, making it the number one tool for SAT prep.

* Twice as many students report using Khan Academy as paying for commercial test prep.

Khan Academy and the College Board developed Official SAT Practice to create personalized tools to help all students, regardless of income level or background, prepare for the SAT and college-level courses.

Official SAT Practice reinforces what students are learning in school by helping them focus on the knowledge and skills most essential for college. And it’s free, for everyone, forever.


Announcing Free LSAT Prep for All

We’re proud to announce we’ll soon offer free, personalized LSAT prep for all.

Every year, more than 100,000 people take the LSAT, the Law School Admission Test. Many test takers have traditionally paid for test prep, which can cost hundreds or even thousands of dollars.

We’re excited to offer a free LSAT practice program designed to help students with the skills they find challenging so that they can show up on test day ready to rock the LSAT.

What’s more, we’re doing this by partnering with the maker of the LSAT, the Law School Admission Council. By working with the maker of the exam, we can help many more people learn the skills they need to do well on the LSAT, in law school, and their careers.

We’re honored the Law School Admission Council has chosen to partner with us, and we’re excited to work together to help level the playing field.

Today’s announcement continues our tradition of providing free, official practice for standardized exams. In 2015, Khan Academy launched free Official SAT Practice with the maker of the SAT, the College Board. More than three million students have used Official SAT Practice at roughly equal rates across income levels, race, ethnicity and gender.

As always, our mission is to provide a free, world-class education for anyone, anywhere. We think free LSAT prep aligns perfectly with our goals. Look for it on Khan Academy in late 2018.
