I do not think so. But you should look into it, anything is possible! :)

Hello Anna,

Thank you for your question - editing unit tests indeed is not possible but we have been taking a look at this kind of feedback for a while now and take it in consideration as we plan the future of Khan Academy.

Thank you for being part of our community!

I'm a teacher from the Philippines, and I'm excited about the possibility of modifying questions, like using money problems in Philippine pesos, to make them more relatable for my students. Thank you, Khan Academy, for providing this platform—it has been a great help in my teaching!
