How to re-verify closed task?
I think I forgot some of the earlier lessons, so I'm trying to review the course and rerun the tasks - possibly using advanced code that I learnt during the course. But it seems like I cannot verify it again even after I reset the task. Is there anyway that I can re-verify my alternative solution?
