Firstly, I am former chinese independent student which graduated 2011 for my form 6 level.

So, I am still under PPSMI that time. Not sure how when PPSMI system abolished.

Note: Different chinese independent high school have different teaching method, i only said out my school teaching method.

1) Not sure how when PPSMI system abolished.

2) Form 1-2 Math and Science all are in Chinese, but Form 3 will teach in English as we need to take for PMR exam.(Note: Not all chinese independent high school take PMR/SPM, as usually take UEC instead of PMR/SPM) That time Math and Science still in English. Form 4-Form 5 Math, Physic, Chemistry all teach in English, only Bio will teach in both Chinese and English due to UEC exam.

3) I think yes, as Form 3, Form 4 & Form 5 is depends on government exam.

4) Not sure how when PPSMI system abolished.

4) Not sure how when PPSMI system abolished.

For PMR Kemahiran Hidup, History & Geografi are BM. Teacher still teach in BM due to exam is BM.

For Junior UEC History & Geografi are Chinese.

For SPM Moral, Sejarah, Accounting, Economic are BM. Teacher still teach in BM due to exam is BM.

No, is depends which CIS that you study.

Example: Chong Hwa Independent High School Kuala Lumpur compulsory take PMR and JUEC on Form 3, SPM on Form 5 & SUEC on Form 6(If you are willing to study Form 6)

Yes, you are right. The student only will get school leaving declaration if dont want study Senior Middle 3.

Yes, you are right too. Maybe they think CIS got good discipline then Sekolah Menengah. But, CIS need to handle JUEC and PMR on junior level, so will busy than Sekolah Menengah.
