I just finished Understanding ROS Topics - Subscribers & Messages from ROS Basics in 5 Days (Python) but the grading seems to be wrong.
On the first time I sent my solution, every checkmark was in green with the exception of the one related to “catkin_make” because I was using catkin tools (as half of the course so far seemed to be using without notice to change) but I fixed it for the default build system on the next try by cleaning the workspace and building it again and everything seemed right.
At the end, none of the checks were giving points despite everything being sent with everything on green so I was wondering if there was something else to do.
Is there a way to reset the course?
Thanks in advance.
