It's not what I mean, we just study a few formulas. I can know it when I have some study from A-level books, i study only tiny little bit. Okey, maybe that's normal. But I take 13 subjects now, Malay, English, Chinese, Chinese Literary, Physics, Chemistry, Biology, Add Maths, Modern MAths, Moral, History,Accountancy, and English for Science and Technology(EST, it will be closed in two years). And I wanna be scientist, and my parents told me that I'm not rational. Because, In my country, even biotech are still a job which few knows,and many scientist in our country starved. My teacher told me, if I really want to succeed in my aim, I have to find that job overseas. And my family can't support me financially. My God!
