I need 11 influences to change the school regulation at FridayBoard to proceed students' quests, but to get the 11th influence, I must finished those students' quests first? All the hints are of no help and now I'm completely stuck at 10 Influences
Most of the people who end up with 10 influence do so because they took the easy way out and only got 1 point from Wilson. I haven't tried to progress that way, so not sure how that if it can be done in the recent update (I am not sure if the staff training with Debbie unlocks in Chapter 1 or not) but you can check out the walk-through, it is very detailed.
The content you get from tricking Wilson and hiring Candy (in addition to 2 influence points instead of 1) is worth playing.
