2017-2018 Online Challenges Open for Submission

What is the difference between Grade Levels in the Autodesk and TI challenges? Autodesk shows all eligible, and the TI one has the No Restrictions box highlighted?

TI challenge is coming soon from the sponsor, so Grade Levels have not been confirmed. We will update the listing to reflect this.
Stay tuned, the TI sponsored challenge will be released shortly!

Thanks for the question,
