The main distinction between pure science and sub-science is Biology .

It really depends whether you are interested in the sciences or not . For one , if you're not interested , it will be harder for you to understand the concepts . There are a lot of concepts to be understood in each of the science subjects . Biology requires intensive reading , retention , recalling and application of facts . It's not easy . But if you're willing to work hard , it's manageable .

Arts is definitely easier in my opinion . I know this because I'm taking Ekonomi Asas too as an extra subject , just reading , some basic calculations and graph drawing and you're good to go . No practical work like what you'd expect in any of the sciences .

If you put in more effort, it'll not be hard, but for those who are not interested they'll be having more stress and problems (understanding..memorizing..etc)

Too much work? Plan your time well and magic happens.
Too many things to rmb?  Put in more effort to think and spend more time, more practice.  



I'll always be here~
