1) Chung Hwa Independent, Jalan Ipoh KL ..... offering SPM and UEC; and
2) Kuen Cheng, Jalan Syed Putra something ..... providing hostel facilities.

I would avoid Confucius KL for in-fighting among board of governors and teachers/HM.

Edit: some Subang guys go to Klang too.

These are my opinion if in selangor/kl area:
1) Chung Hwa KL, undeniably that they are the best chinese independent school in selangor/kl area, balanced focusing on SPM and UEC
2) Kuen Cheng, more focussed on SPM, most of the students gave up UEC (I heard they use final year to complete all the UEC subjects)
3) Tsun Jin, i graduated from there, same as Chong Hwa (balanced focusing on SPM and UEC), but it is quite stressful to study there (from 7.00 until 4.10pm, Monday to Friday and almost every Saturday have cocuriculum) and the traffic jams is the biggest issue lol
4) Hin Hwa, it can be considered if final goal is UEC, last year they achieved colourful results on UEC, but they not too focused on SPM
