The life of a pre-enlist student for the army would be relatively considered calm and easygoing when compared to the graduate enlists.
They had boring but important classes which most didn't take seriously. The training was mandatory but it wasn't as extensive. They weren't on a strict dietary plan with military control over everything.
Plus they could always go home at the end of the day which was great. They weren't forced to sleep on a military-approved single bed that was so hard you would think you were sleeping on a rock
On Starnet they described pre-enlist school days as a vacation before the hard work actually begins. It was like the Christmas holidays before January comes knocking with bills and problems. One citizen had compared it to boy scout camp.
