[Topic] Wallace (Deep Sea) [Question] I am confused between the 7 and 5 minutes in the description, how much time do we really have? [Answer] 
If you complete the course within 6 minutes, without the oxygen tanks, okay. The divers will survive. However, these tanks give you an extra minute of air to get the divers to the surface. The divers have 6 minutes of air with them and that is the time for this course. The oxygen tanks represent the extra minute of air for the total of 7. (The 5 in the course description has been changed to a 6, noted by the number in red).
