同学,你好 
我已经帮你询问过正在UPM修读EKONOMI的第三年学长了,我一个一个问题回答你。
1. EKONOMI是否和STPM所学的相近还是完全不同呢?
是接近相同的,第一年所学习到的东西,基本上与中六学习到的是差不多一样的,但是到了第二年开始,学习到的东西就有一点深了。
2. 是否要读很多关于政治,还有计算的东西呢?
EKONOMI 这一科,基本上与政治没什么关联,但是政治还是会影响经济。至于计算方面,根据学长的讲法,是的,EKONOMI这一科,的确需要读到很多计算
的东西,而且算是占了很大部分。
3. 是否和数学有很大关系呢?
是的,经济学和数学有着一定的关系,想请问一下,你的数学成绩如何?是否符合了EKONOMI这一科系的syarat khas呢?
升学愉快
