Dartmouth College, long known as a place where heavy drinking was central to social life, appears to be making significant progress in reducing dangerous levels of drinking, The Boston Globe reported. A series of reforms -- many of them involving undergraduates -- have been put in place. For example, undergraduates who have not been drinking play a key role in monitoring parties. A sign of progress is that this year only 31 undergraduates were hospitalized for having blood alcohol levels at the dangerous level of 0.25 percent. Two years, ago, 80 students were hospitalized for such blood alcohol levels.
