Sending kids to SJK especially SJKC is not entirely for the mandarin language (afterall from 2002-2012 the teaching medium for science and maths were english). The main purpose is actually for the learning motivation and the teaching environment which is culturally similar to schools in east asia.. where their goal is to excel in exams. Almost every high performing SJKC in KL will have after school classes to further boost the main UPSR subjects and perform hours of revision on past year questions to better prepare the kids for the actual exam.
