Hello!, first of all thank you in advance for all the future replies to this thread.
I am writing to ask you about the possibility of taking back badges manually, or using an automatic condition or requirements. The idea is to remember the students no to relax with an specific content which in a previous test he/she was awarded with a badge. For example if in the first year they had a badge for square roots and in the second year they fail badly another test about square roots, we could take back the first year badge to remind them that is it not just about passing tests but to understand the specific content for live. So in this case they should take again the first year test to regain the badge.
I hope this makes sense.
