Effect of an Addendum/ Cumulative GPA

<p>I was wondering how much of an impact an Addendum would have in explaining the discrepancy between my 3.75 cumulative gpa and my 3.85 degree gpa. Would the fact that the single course that brought my gpa .1 was a course that I took during my high school senior year after dealing with family issues the three years before?</p>

<p>Thanks in advance for taking the time to read this, I find this forum to be very helpful.</p>
