figuring GPA's

[boomer2o5]

<p>A friend of mine at school has asked me this several times so I thought maybe you CC'ers would know. He has a 2.8 cumulative GPA and he is in his 2nd semester of his junior year. If he were to get around a 3.6-3.8 his senior year, both semesters how much would this improve his gpa? (note- only our 10,11th, and 12th grade grades are calculated into our GPAS)</p>
