Level 45 on day 6 is barley possible. However, with all the disconnects and game crashes I cant train while away form the computer. If it would not disconnect so much, I would have made day 6 rewards on time. Also they have nerfed the Lab now, and getting tons of experience is difficult imo.
I beat it with over 500 points and get 30k exp.

IMO level 45 should be day 7 and Plague Professor should be day 6, the plague professor can be beat when you are level 40 or lower without vip
