Calculate GPA

Could you please help me calculate my GPA, desperately need it for my American uni application

I used this site as my guide for calculating. Math is below, but the result I get is 2.94.


(4x(44+17))

+ (3x(12+37+51))

+ (2x(13+24+38))

/

(133 + 78 +25)

=

(244 + 300 + 150)

/

(133 + 78 + 25)

=

694/236

= 2.94
