Sam came back to the second floor. From what he saw this floor is the most occupied of all, because no matter what batch the participants are from, they have entry to this floor and not many of them are interested in formations.
The first batch candidates including Sam only went to the formations because they knew the importance of the formations.
Many may look down on them, but if there is a proper formation in place, it would increase the controller's winning rate by many levels and learning about formations will at least make them immune to getting struck in a formation and let them escape even if they are not able to lay one themselves.
Of course, Sam being a formation master himself is one of the reasons for him to clear the first floor.
As for second floor, it is mostly focused on the aspects of a person in battle like speed, strength, defense, battle awareness and tracking the enemy in long range.
