Hi leticiabadilloprieto,

Due to the way that challenges are structured, it's unfortunately not possible for teachers to directly see the code submitted by students for code challenge assignments. Our team is aware of this issue, but unfortunately I don't have a timeline as to when this feature might be added.

However, there is a workaround for this:

1. After completing the challenge, students will need to click the Spin-Off button on the code editor. This will save a copy of their challenge code to their profile page.
2. You can then view their submissions via the Projects tab in your class. Make sure the dropdown menu says "All projects".

I hope this helps! Please let me know if you have any additional questions!
