1. ከ 100 ያገኛችሁትን ወደ Grade. ትቀይራላቹ(A+,A,A-,B+....) 2.እያንዳንዱ Grade የራሱ ነጥብ አለው(ለምሳሌ A=4 , B+ = 3.5 ....) 3.የእያንዳንዱን ነጥብ በ credit hour አባዝታችሁ የመጣውን ውጤት ትደምራላቹህ። 4.በመጨረሻም ለTotal Credit hour ማካፈል(1st semester total credit hour 19 ነው) ለምሳሌ:student 1 Aplied=86=>  A= 4 English=90=>  A+ =4 physics=82=>  A- =3.75 Chemistry =78=> B+ =3.5 python=81 =>  A- = 3.75 Logic=92 => A+ = 4  ቢያመጣ Applied=  4 × 4(credit hour) =16 English= 4 × 3(credit hour)= 12 Phy  = 3.75 ×3(credit hour)=11.25 Chem= 3.5 × 3(credit hour)= 10.5 Logic = 4 × 3(credit hour) =12 Phyton= 3.75 ×3(credit hour)= 11.25                                       =>  total =73.25 Result= total/total chr             =73.25/19 =3.85 So የ student A result=   3.85
