My guess is that the lab always fails in 807 due to incorrect cd usage. The failure can be a crash or wrong answers.
The lab running to completion does not mean that things are OK. Someone needs to follow the code carefully in order to correct the cd usage. One possibility is to step through 807 side-by-side with 806 and see where things go bad. On Wed, May 30, 2018 at 11:53 AM, J.
