Gpa calculation help?

Since none of us knows how many credit hours those 4 courses you claim you are going to take  nor how many courses you took or how many credit hours they carried OR what your exact grades. I'm using plus minus grades, you got in those courses, NO ONE can calculate your possible cumulative GPA FOR you. Assuming you sure going to get As in all 4 courses is very dangerous. I gave him on calculating my cumulative GPA whilshI was working on my SECOND bachelors degree with a major kin geology. At that point all I cared about was graduating with a cumulative GPA of 3.0000 or higher AND surviving geology field camp. I did BOTH. I also got accepted to graduate?school because of my high general aptitude GRE scores, NOT my cumulative GPAs or having 2 bachelors degrees. 

1. The other answer gives the correct formula.

2. Since you omitted necessary data, your exact GPA cannot be determined.  My estimate would be in the area of 3.38 to 3.45.

3. Computing averages is 8th grade level math.  College students who cannot figure their GPA have a serious academic deficiency.  Some "back to the basics" style studying is in order, and will be of benefit to you in either future studies or employment.
