Grading System in Chinese Primary Schools

It has been almost 9 months since my boy's transfer to his present school. Other than missing some of his ex-classmates, a few of them who used to be close to him, we kind of settle ourselves into our new routine comfortably. Recently, his ex-classmate, a boy called me on my mobile and asked to speak to my boy. That boy called to say hi and checked on how my boy had been doing. How sweet... My boy still misses a few of his ex-classmates as they have so much in common but this will be a post entry for another day.

Back to today's post, I didn't realize until I went through one SJKC and now another that grading system for each and every school might differ. The previous school takes 6 subjects (i.e. BM & Chinese Pemahaman papers only), English, Science Chinese, Maths Chinese and Moral papers) as its core subjects to determine the pupils' positions in class and the whole standard. However, his present school adopts the UPSR grading system of 7 core subjects i.e.BM & Chinese, both Pemahaman & Penulisan papers, English, Science Chinese and Maths Chinese. When I got my boy's report card for the first time from his previous school, I was surprised that both BM and Chinese Penulisan papers were excluded from the calculation of overall performance and his then class teacher confirmed that it would stay that way until standard 5, she wasn't sure though if it would stay the same for standard 6.
 

Personally speaking, I like the grading system of the boy's present school which is to adopt the UPSR system though it can be a risky one as if one slacks the Penulisan papers, expect your overall performance to nosedive and the kids' self-confidence to be badly affected. 

 Mommies with primary school going children, do the schools that your children go to adopt my boy's previous or present school's grading system?
