Last year I had a first semester GPA of 3.37. That year I did not go on newschoolers during school whatsoever.
This year, I am on newschoolers in just about every class and my GPA boosted to 3.88! I'm thinking it might be the stress relief and such, having something to look forward to- an incentive. But big ups to the power of newschoolers to boost my GPA.
