Talk to upperclassmen also
Anyone visiting now and speaking only to plebes will hear a mix of sentiments, especially since the 2013 class has not yet been recognized. The plebes he encounters most likely will be pretty stressed and worn out and may not present a pretty picture of KP. Therefore, I think it is important for your child to seek out other voices, especially 1st classmen who have run the gauntlet and have persevered. This is a low point in the year for the plebe class and an intellectual understanding of that will help mitigate the emotional responses your son might hear from the plebes. You want him to make an informed decision!
