The training missions pack has been retired as of August 27th 2018. It has been replaced by the Cyber Robotics 101 pack.
This means progress made in this pack has been undone.
The transition to the Cyber Robotics 101 pack includes additional missions and content that improves the offering of the Training Missions, now retired. If you like we can reinstate the Training Missions pack for you and/or your students. Alternatively, we are working on porting progress from the Training Missions to the relevant missions in CR101.
If you want to retrieve the Training Missions Pack and your progress, please contact support.
