Hi Daniel,

Do you mean something similar to a reset feature, but not for the whole test and just a section? 

I'll be sure to add your suggestion to our list, as a lot of Khan Academy students have shared this request with us! 

Thanks! 

There used to be a button at the end of every practice exercise that said something like "try again" but they removed it. I used it all the time!

And I'm not talking about a "reset" type of button where you can stop in the middle of a practice and start again at the beginning. Just a basic I-want-to-practice-this-skill-more button at the end when completed. I have no idea what useful purpose there was in removing it.
