I score better grades for subjects that I actually have an interest in. This might sound obvious to some people, but it took some time for me to realize that.

Take Maths and Geog for example.

I seriously enjoy doing Maths and I usually attempt to complete any Maths Supplementary Exercise as soon as I get it. I have an interest in it. My GPA in Maths? 4.0.

I won't say I enjoy doing Geog, but I find it extremely interesting. I mean, how can studying the very planet you are living on not be fascinating? Definitely my pick over Lit and History. I have an interest in it. My GPA in Geog? 4.0.

Now, for the other side of the story. Subjects (specially Sciences) such as Chemistry. I'm no Chem enthusiast. I have no particular interest in Chemistry. My GPA for Chem? Let's just say it's not that high.

This is only one such example, but I've found out this important secret (yet oh-so-simple) - Enjoy the subject you are doing, and you'll surely score high for it.

And from now on, I intend to like the subjects that I don't do that well in more. Whether I like it or not. (How ironic :/ )

My personal take. ._.
