Forgive me, but doesnt the CGPA of STPM involve all the 4 subjects?
For example;
If your semester-specific grade is as follows:
PA- A, A-, A-, B+
Chemistry- A, A, A-, A
Physics- B+, B, A-, B
Maths- B+,B+, A-, A-
And maybe your final subject grade is:
PA: A-
Chemistry: A
Physics: B+
Maths: B
Then your CGPA will be the average of your 4 subject's final marks:
(4.00+ 3.67+ 3.33+ 3.0)/ 4= 3.50
