I'm really glad you're not the one that marked my SPM paper
Btw, you got your bolded part wrong. You really shouldn't be so critical about our exam system. While education in Malaysia may suck, the basic education system and the exams are modeled after the same system that exist all around the world.
First of all, SPM/O-Levels/STPM/A-Levels(British system) and TER and SAT all grade students relative to the whole batch of students that took the particular exam.
For the British system, marks ranging from 0-100 is awarded for every subject testes. Then the marks for every student will be sequence from the highest to the lowest and if you would to graph a probability density function for all the values, you'd get a curve and the data would like follow a normal distribution hence the term
curved grading. So the exam board decides the top 10% gets an A the next 20% gets a B and so on. It's probably not 10%,20%,30%... in reality, each exam board has their own system of setting the percentage cut off for each grade. The marks range for a certain grade will definitely be different for each subject since the top 10% for Biology might be people getting above 60 marks while the top 10% for Physics might be people getting above 90 marks.
of course they lay out the results in order, and if the cohort size is big enough, it will follow the bell shaped normal curve, or close to it........
however, a's are not always given based on the percentage of cohort........but on the actual cut off marks.........which is why the number of a's keeps on increasing as students get better at spotting questions, and regurgitate sample model answers.......this happens with spm, and it happened with a-levels........how else can you explain in some subjects, 25% of students gets a grades........that is why the band grade system does not stratify the top a band adequately.......

The Australian TER is similar but it's main difference causes it to suck IMHO. Similarly all subjects are curved but the TER percentile itself it based on the sum of the adjusted scores of all 4 subjects plus 50% of the adjusted score of the fifth. And then you're awarded the top 97.5 percent top 97.0 percent and so on in 0.5 percent decrements. I see it as a big disadvantage if the grades for each subject can't be assessed independently.
you are mistaken..........
the steps are in 0.05 steps..........ie you get ters like 97.45, 97.50, 97.55 etc........
yes the ter is an overall ranking, each individual subject is also graded in the band form, so you do know how you perform in individual subjects........eg, in sam, you get a 20 step banding system, from a top of a20, a19, a18, a17, b16 and down........
i consider it the best grading system, where the unis have BOTH the overall rank of the student in relation to his peers without the effects of variations of the difficulty of the papers......and the individual grades of each subject taken........to help them select students, especially for critical courses......

The SAT isn't really a raw marks system. For the SAT 1 the total score you can get in each component is 800 and the 3 combined will yield 2400. In the exam, there you don't get marks for answering questions up to 800. Except for the English essay question, you get 1 point for a right answer, 0 for a wrong and -0.25 for a wrong one. Somehow or rather the total marks you get will be sequence and will be given a corresponding SAT score from 0-800. However, it's not as simple as it seems. Even if you answer all questions wrong, you don't get 0. You answer no questions you gets something around 200 and you normally don't have to get everything right for an 800. Collegeboard, the people behind SAT claims they whatever they method is, which they never explain, provides the best way to compare students academic ability.
i know sats is not really the actual raw marks, but it is as close as you can get to raw marks, compared to either the band format of a-levels, or the percentile ranking of ter........
