i think i've explained this before. u cannot calculate CGPA directly from marks percentage. i've looked into the worldwide convention for this, and even UiTM, which uses unconventional method, still interprets the CGPA through grade-point value (or kaedah wajaran).
the ministry complies to ISO. so it has to move based on the established methodologies only, and cant just suka2 create a new, untested system and implement it nationwide. sure, it's not disclosed, but having been in the system for over 12 years, i can assure u there are many people in the ministry who will buat bising if anyone tries to implement anything unconventional. not everyone in the ministry of education are loyal to the current government.
so bottom line is, it has to be based on a conventional, established method. meaning:
a grade will have an absolute value (grade point). since 4.00 is the highest, we can assume A is 4.00.
at university level, u dont just average it. u have to multiply the grade point with the credit value (weightage of the subject). a 2 credit subject will weigh less than a 6 credit subject. if u take both subjects at the same semester, u can calculate it like so:
2 credit subject scored C (2.00) and 6 credit subject scored A (4.00):
((2 x 2.00) + (6 x 4.00))/(2+6)
= 3.50cgpa.
let's reverse it. 2 credit subject scored A (4.00) and 6 credit subject scored C (2.00):
((2 x 4.00) + (6 x 2.00))/(2+6)
= 2.50cgpa.
do u see the calculation? if u score a 2 credit subject but suck at the 6 credit subject, u will only score 2.50cgpa. the heavier the subject's credit, the more it will impact ur cgpa. so in this case, what we need to find out is what each semester's weightage is. only then we can figure out the cgpa.
The weightage of each paper is disclosed to the public. You can see it in the syllabus. The students are all aware of the weightages
For example, for Mathematics (T), paper 1 to paper 3 each carries a weightage of 26.67% while paper 4 carries 20%.
Pengajian Am is different. Paper 1 and paper 3 are 29%, paper 2 is 20% while paper 4 is 20%.
Let me stressed that for the same subject and same weightage (and hence same credit hour since MOE fix the number of periods we should have for one week), we observe different final grades for the same semester grades.
Meaning, for Chemistry, in numerical paper order, those who score A/B+/A-/A might get a final grade of A, and those who score A/B+/A-/A might also get an A-. Weightage has been taken into account, and printed on the result slip.
You can totally not predict what your final grade might be. Just as we couldn't (I am an STPM 2013 graduate).
The evidence is overwhelming. You can argue, and I agree whole-heartedly, that the calculation for final CGPA based on marks is extremely unfair and unconventional, but it is a fact. Perhaps you can argue with MPM for the sake of other STPM graduates in the future?
We believed what MPM told us on the phone because we have tried all possible ways to calculate the final grades, but none worked and none could explain the discrepancy between two different people who get same semester grades for the same paper (meaning, example, for Physics, both get A for first semester, A- for second semester, and A for third semester, and A for paper 4, but for final grade one get A and another A-). MPM's answer is the only one that could explain the discrepancy observed - or it does not explain at all, perhaps, but at least it tells us why it exists and why none of our methods worked.

We all know that the percentage is not given out to candidates. But exactly
how the calculation is, no one knows. Even if we do not know the percentage we get, at least it should be known to student on how the calculation is being done. Otherwise, it would be just 'study smart, get good results' without knowing what is the minimum people should be aiming for. Take SPM for example. People want A+, they aim for 90% and above. In STPM, well, it's just study, study, study.
Ouh, get 4.00. Save! Get 2.67? What to do? Things like that.
And also, teachers are not given briefing on how the co-curiculum marks should be calculated too. Should it be calculated by semester or by Lower Six & Upper Six. And how the co-curriculum will be added to final results (to be honest, I don't even know if it's 90%/10% in STPM).
Technically, how UPU calculates the 90% academic and 10% marks are your duty to find out, not the school, as UPU is not part of the school.
Ko-k falls under the jurisdiction of MOE, not MPM. Like in previous years, KO-K marks are calculated by year, not semesters.
And yes, this is why STPM is so unfair. You do not know what marks you need to get an A or a B+. The grades you get after each semesters may be extremely surprising. You thought you could do all the questions, but you might get only a B+ (like I did for sem 2 physics), you might think you can't do lots of questions, but you could get an A in the end (like my ulangan 1 physics).
MPM is unpredictable. I've spent one and a half year trying to fathom them, but we gave up eventually.
Don't waste your time. Just do your best.
