GSC is three,
GSC stands for the Glasgow Coma Scale which is a basic neurologocial rating of consciousness. 3 is the worst. The scale goes up to an aggregate of 15 and rates eye, verbal, and motor response on a 1 to 4, 5, or 6 scale, respectively. 3 means he got a 1 in each category which is unresponsive across the board, so he was out cold. Can’t get worse than that.
