i have two kids in college. Both are doing about the same as in HS; mostly all A’s; each one has one or 2 B’s.
However, the biggest difference we see with GPA is this: an A- = 3.67 in our colleges. In HS; we had A- and A all = 4.0. They both have a few A- grades in college, and that’s brought their GPA down a little. I will say, now that they are into their hard classes for their majors, they are really working hard and seem to take it all a little more seriously than HS.
