From what I've seen in previous forum posts regarding this topic, it's unfortunately impossible to see how many scores you've mastered overall. However, the progress tab in your profile has information on what skills you've leveled up and whatnot.

From what I know, u used to be able to, but then like 1000000000000 badges got retired and also removed seeing how much skills you have mastered

Hi there! 

Thank you for your feedback on having a way to see skills mastered on the site! We truly appreciate your feedback and we are constantly working on improving the site. 

Best, Jo

Hi everyone,

I have some great news to share with you!

Based on feedback that you and other learners shared with our team, Khan Academy has recently redesigned the Course and Unit Mastery pages and introduced an overview of the skills in a single course so you can tell in a glimpse what skills you’ve mastered and those that still need to be completed!

To know more about this change, please take a look at the article Update: New mastery progress visualization on Course and Unit pages.

Most importantly, we want to thank you for taking the time to share your feedback to help make Khan Academy a better learning resource for everyone. We take all feedback to heart and appreciate you sharing your ideas with us.

Thank you so much for helping us improve Khan Academy!

Kind regards,
