Walao eh...POP QUiZ!

Today was an unlucky day for me. Tiring! As usual, I thought it is going to be a boring lecture where I have to occupied myself by copying down all the mathematical equations on displayed on the screen. But! Out of a sudden, the lecturer said he was going to give us a surprise and indeed, it was a surprise. We were only given one mathematical question to solve and yet i couldn't do half of it. Disappointing, but it's a wake-up-call for me. Guess I have to declare that my greatest enemy now is DIFFERENTIAL EQUATION and I am gonna defeat it! This is my new year's resolution. LOL!
