Hi mmarilyn-berry 

Glad you're enjoying the course. I think you have already figured out that there already is an updated version of the Vonnbots.

But'll post the link here just in case.

And I'm pretty sure I added all the 2.8 version of the files into that course too.  (but the videos still show 2.7x)

By the way, make sure you upload your exercises if you haven't already.  I give all the submissions a review.

This is the best way to improve.
