Back in June, I challenged the entire Khan Academy community to join me in a summer surge of learning and see how many energy points they could earn. Today, I’m excited to announce the results:
209,161 learners rose to the challenge and earned more than 50,000 energy points. For their achievements, they have been awarded the Summer Surge badge:
Big congrats to everyone who earned this badge!
Of the folks who earned the Summer Surge badge, 53,035 of them earned more than 145,878 energy points, which was my summer total. These summer superstars have been awarded the I Beat Cam badge:
Super huge congrats to everyone who beat me! Your work is both inspiring and humbling. To see whether you earned one of these badges, log in to Khan Academy, go to your profile, and click “badges.”
My summer learning goals
Two of my main objectives this summer were learning to unicycle and learning to juggle clubs. I had some struggles along the way…
…but with practice I learned both skills and even put them together for the Khan Academy talent show:
I also learned some finance and economics on Khan Academy, two subjects I’m interested in but never studied in school. It was a blast! Seriously, it’s hard to beat the thrill of truly wrapping your mind around a new concept or acquiring a new skill.
Thank you to everyone who participated in the Summer Surge! What did you learn over the summer, and what are you hoping to learn in the months ahead? Let me know in the comments below!

Every day, learners around the world visit Khan Academy to brush up their skills and explore new subjects. Maybe you’ve studied math on Khan Academy, and maybe you’ve wondered how artists, scientists, and engineers use math to build amazing things.
To help answer that question, Khan Academy, with support from Disney, teamed up with Pixar Animation Studios to create Pixar in a Box: a free online curriculum that shows how Pixar artists use the concepts we all study in school to create their amazing movies.
Through video lessons, interactive exercises, and hands-on activities, you can learn how Pixar artists use math to solve design problems at each stage of the creative process. In particular, you’ll discover:
- How large swarms of robots in “WALL•E” were designed using combinatorics
- How a field of grass was created in “Brave” using parabolic arcs
- How simple models are transformed into realistic characters using weighted
- How animators bring characters to life with the help of animation curves
- How sets are constructed using geometric transformations
- How all of Pixar’s images are painted using simultaneous equations
But this is just the beginning. In the years ahead, we’ll explore many other subjects, including science, computer science, arts, and humanities.
We’re excited to hear your feedback so we can make Pixar in a Box even better, so let us know what you think in the comments below. We hope you’ll have as much fun exploring Pixar in a Box as we did creating it!

Our mission at Khan Academy is a free, world-class education for anyone, anywhere - but we can’t do it alone. To reach more learners and cover more subjects, we need more explainers to create more content.
That’s why we launched the Khan Academy Talent Search this May - to find great explainers and amplify their voices. About 4,000 folks submitted videos to the contest, sharing 8,000 lessons with learners around the world. The quality and creativity of these submissions blew us away!
After reviewing all the entries, we’ve selected 10 promising winners:
- Dan Quinn, postdoctoral student in physics
- Dara Brady, fifth-grade teacher
- David Rheinstrom, editorial director at Leftside RightSide
- George Zaidan, freelance science video creator
- Grant Sanderson, recent graduate of Stanford University
- Guillaume Riesen, doctoral student in neuroscience
- James Portnow, video creator at Extra History
- Sage Simhon, high school student
- Sudhir Murthy, undergraduate student at the University of California, Riverside
- Tony St. John, chemistry professor at Western Washington University
Last week, we brought all the winners to California for an immersive workshop on creating videos and cultivating channels. These 10 incredible explainers visited the Khan Academy and YouTube teams and even took a selfie with Sal.
Sound exciting? Although this year’s Talent Search has ended, you can still help us bring more content on more subjects to learners around the world. Check out our careers page for current openings on our content team, or tell us about other YouTube channels and educational websites you think we should know about here.

This spring, Stanford Consulting - a nonprofit, student-run organization - ran a survey to learn about the impact that Khan Academy has had on the educations of current college students. These students were asked whether they “found Khan Academy meaningful to their education” and whether they were the first in their family to go to college. The results are in, and today we’re excited to share some of the key findings.
Of the students who responded to the survey…
- 65% of Stanford students found KA meaningful to their education (out of 504 surveyed)
- 57% of students in other top schools* found KA meaningful to their education (out of 159 surveyed)
- 64% of first-generation college students (the first in their family to go to college) at these schools found KA meaningful to their education (out of 164 surveyed)
*Surveyed schools include Harvard, Princeton, the University of Pennsylvania, UC Berkeley, Caltech, Notre Dame, MIT, Vanderbilt, and Yale.
We’re thrilled to see how many college students have benefited from Khan Academy and to hear their stories. One first-generation student from Stanford shared the following note with us:
For all the times I couldn’t turn to my parents for homework help, I had Khan Academy videos to help me. Khan Academy was the private tutor that my family could not afford. For all the times I wanted to learn for the sake of learning, I would pick from the hundreds of Khan Academy videos.

Hi, I’m Cam from Khan Academy, and I challenge you to join me for a surge of summer learning!
I can’t unicycle yet, but I’m learning. My other summer learning goals are focused around biology and economics.
No matter what you choose to learn on Khan Academy, you’ll be eligible to earn two special badges:
Get the Summer Surge badge by earning at least 50,000 energy points this summer.
Get the I Beat Cam badge by earning more points than I do this summer.
The challenge runs from the June 23rd through August 28th (official rules below). There’s no special signup to earn these badges; all you have to do is start learning now!
Not sure what you want to learn this summer? Here are three ideas:
Supercharge your math skills. For example, if you’re headed into Algebra I, jump into the Algebra I mission and get started on those mission foundations (pre-requisites) to make sure you start the school year strong!
I look forward to learning alongside you this summer. You can track my summer learning progress by watching my KA profile or by following me @icamlearn on Instagram or Twitter. Let me know what you’re learning using the hashtag #KASummerSurge.
Your fellow learner,
All points earned anytime from the very start of the day (PDT) on June 23rd to 11:59pm PDT on August 28th will count towards these badges.
Badges (described above) will be awarded only after the contest has ended. I’ll give everyone their badges on August 31st.
Who is beating me so far?
I have earned a total of 0 points so far this summer (as of June 23rd), so I imagine lots of people are beating me right now. But, remember, badges are awarded at the end of the summer (after August 28th), and you’ll only get the “I Beat Cam” badge if you earn more points than I do over the course of the entire summer.
Check back here in coming weeks to see a list of usernames that are beating me.
UPDATE (July 16th): Because so many of you have earned so many points, I’ve decided not to post a list of everyone beating me - it would fill up the entire screen! Instead, here are instructions for how to figure out if you’re beating me:
Step 1: Calculate your starting points (points earned since June 23rd).
- Go to your activity page (profile–>progress–>activity).
- Set a custom range to see your progress since the 23rd.
- Sum your daily energy points to find your summer earnings.
- Subtract your earnings from your current KA energy points to find your starting points.
Step 2: Spin of this awesome CS program and input your starting points.
Step 3: Watch the program calculate whether or not you’re beating me :-)
