Maintaining a 3.0 your freshman year is not hard at all in my opinion. Just go to class and everything should be fine for him! There is a formula, but I can't remeber the exact numbers, but basically you get so many points for an A,B,C,D, and F, add those up and divide by the number of credits you are taking! Im not sure if that is a universal formula, but thats how it is at ODU. Good Luck to your DS
